Add data anonymizer (#9863)
### Description

The feature for anonymizing data has been implemented. In order to
protect private data, such as when querying external APIs (OpenAI), it
is worth pseudonymizing sensitive data to maintain full privacy.

Anonynization consists of two steps:

1. **Identification:** Identify all data fields that contain personally
identifiable information (PII).
2. **Replacement**: Replace all PIIs with pseudo values or codes that do
not reveal any personal information about the individual but can be used
for reference. We're not using regular encryption, because the language
model won't be able to understand the meaning or context of the
encrypted data.

We use *Microsoft Presidio* together with *Faker* framework for
anonymization purposes because of the wide range of functionalities they
provide. The full implementation is available in `PresidioAnonymizer`.

### Future works

- **deanonymization** - add the ability to reverse anonymization. For
example, the workflow could look like this: `anonymize -> LLMChain ->
deanonymize`. By doing this, we will retain anonymity in requests to,
for example, OpenAI, and then be able restore the original data.
- **instance anonymization** - at this point, each occurrence of PII is
treated as a separate entity and separately anonymized. Therefore, two
occurrences of the name John Doe in the text will be changed to two
different names. It is therefore worth introducing support for full
instance detection, so that repeated occurrences are treated as a single
object.

Add security notices on PAL and CPAL experimental chains. (#9938)
Clearly document that the PAL and CPAL techniques involve generating
code, and that such code must be properly sandboxed and given
appropriate narrowly-scoped credentials in order to ensure security.

While our implementations include some mitigations, Python and SQL
sandboxing is well-known to be a very hard problem and our mitigations
are no replacement for proper sandboxing and permissions management. The
implementation of such techniques must be performed outside the scope of
the Python process where this package's code runs, so its correct setup
and administration must therefore be the responsibility of the user of
this code.

Add security warning to experimental SQLDatabaseChain class. (#9867)
The most reliable way to not have a chain run an undesirable SQL command
is to not give it database permissions to run that command. That way the
database itself performs the rule enforcement, so it's much easier to
configure and use properly than anything we could add in ourselves.

Initial commit for comprehend moderator (#9665)
This PR implements a custom chain that wraps Amazon Comprehend API
calls. The custom chain is aimed to be used with LLM chains to provide
moderation capability that let’s you detect and redact PII, Toxic and
Intent content in the LLM prompt, or the LLM response. The
implementation accepts a configuration object to control what checks
will be performed on a LLM prompt and can be used in a variety of setups
using the LangChain expression language to not only detect the
configured info in chains, but also other constructs such as a
retriever.
The included sample notebook goes over the different configuration
options and how to use it with other chains.

###  Usage sample
```python
from langchain_experimental.comprehend_moderation import BaseModerationActions, BaseModerationFilters

moderation_config = { 
        "filters":[ 
                BaseModerationFilters.PII, 
                BaseModerationFilters.TOXICITY,
                BaseModerationFilters.INTENT
        ],
        "pii":{ 
                "action": BaseModerationActions.ALLOW, 
                "threshold":0.5, 
                "labels":["SSN"],
                "mask_character": "X"
        },
        "toxicity":{ 
                "action": BaseModerationActions.STOP, 
                "threshold":0.5
        },
        "intent":{ 
                "action": BaseModerationActions.STOP, 
                "threshold":0.5
        }
}

comp_moderation_with_config = AmazonComprehendModerationChain(
    moderation_config=moderation_config, #specify the configuration
    client=comprehend_client,            #optionally pass the Boto3 Client
    verbose=True
)

template = """Question: {question}

Answer:"""

prompt = PromptTemplate(template=template, input_variables=["question"])

responses = [
    "Final Answer: A credit card number looks like 1289-2321-1123-2387. A fake SSN number looks like 323-22-9980. John Doe's phone number is (999)253-9876.", 
    "Final Answer: This is a really shitty way of constructing a birdhouse. This is fucking insane to think that any birds would actually create their motherfucking nests here."
]
llm = FakeListLLM(responses=responses)

llm_chain = LLMChain(prompt=prompt, llm=llm)

chain = ( 
    prompt 
    | comp_moderation_with_config 
    | {llm_chain.input_keys[0]: lambda x: x['output'] }  
    | llm_chain 
    | { "input": lambda x: x['text'] } 
    | comp_moderation_with_config 
)

response = chain.invoke({"question": "A sample SSN number looks like this 123-456-7890. Can you give me some more samples?"})

print(response['output'])


```
### Output
```
> Entering new AmazonComprehendModerationChain chain...
Running AmazonComprehendModerationChain...
Running pii validation...
Found PII content..stopping..
The prompt contains PII entities and cannot be processed
```

Add py.typed file to langchain-experimental. (#9557)
The package is linted with mypy, so its type hints are correct and
should be exposed publicly. Without this file, the type hints remain

Added SmartGPT workflow (issue #4463) (#4816)
# Added SmartGPT workflow by providing SmartLLM wrapper around LLMs
Edit:
As @hwchase17 suggested, this should be a chain, not an LLM. I have
adapted the PR.

It is used like this:
```
from langchain.prompts import PromptTemplate
from langchain.chains import SmartLLMChain
from langchain.chat_models import ChatOpenAI

hard_question = "I have a 12 liter jug and a 6 liter jug. I want to measure 6 liters. How do I do it?"
hard_question_prompt = PromptTemplate.from_template(hard_question)

llm = ChatOpenAI(model_name="gpt-4")
prompt = PromptTemplate.from_template(hard_question)
chain = SmartLLMChain(llm=llm, prompt=prompt, verbose=True)

chain.run({})
```


Original text: 
Added SmartLLM wrapper around LLMs to allow for SmartGPT workflow (as in
https://youtu.be/wVzuvf9D9BU). SmartLLM can be used wherever LLM can be
used. E.g:

```
smart_llm = SmartLLM(llm=OpenAI())
smart_llm("What would be a good company name for a company that makes colorful socks?")
```
or
```
smart_llm = SmartLLM(llm=OpenAI())
prompt = PromptTemplate(
    input_variables=["product"],
    template="What is a good name for a company that makes {product}?",
)
chain = LLMChain(llm=smart_llm, prompt=prompt)
chain.run("colorful socks")
```

SmartGPT consists of 3 steps:

1. Ideate - generate n possible solutions ("ideas") to user prompt
2. Critique - find flaws in every idea & select best one
3. Resolve - improve upon best idea & return it

Fixes #4463

Fix issue 7445 (#7635)
Description: updated BabyAGI examples and experimental to append the
iteration to the result id to fix error storing data to vectorstore.
Issue: 7445
Dependencies: no
Tag maintainer: @eyurtsev
This fix worked for me locally. Happy to take some feedback and iterate
on a better solution. I was considering appending a uuid instead but
didn't want to over complicate the example.

- [x] Raise TypeError in operator methods for unsupported things 
- [x] Implement dict which calls values in parallel and outputs dict
with results
- [x] Merge in `+` for prompts
- [x] Confirm precedence order for operators, ideal would be `+` `|`,

- [x] Add support for openai functions, ie. Chat Models must return
messages
- [x] Implement BaseMessageChunk return type for BaseChatModel, a
subclass of BaseMessage which implements __add__ to return
BaseMessageChunk, concatenating all str args
- [x] Update implementation of stream/astream for llm and chat models to
use new `_stream`, `_astream` optional methods, with default
implementation in base class `raise NotImplementedError` use
