Add support for Qdrant nested filter (#4354)
# Add support for Qdrant nested filter

This extends the filter functionality for the Qdrant vectorstore. The
current filter implementation is limited to a single-level metadata
structure; however, Qdrant supports nested metadata filtering. This
extends the functionality for users to maximize the filter functionality
when using Qdrant as the vectorstore.

added Wikipedia retriever (#4302)
- added `Wikipedia` retriever. It is effectively a wrapper for
`WikipediaAPIWrapper`. It wrapps load() into get_relevant_documents()
- sorted `__all__` in the `retrievers/__init__`
- added integration tests for the WikipediaRetriever
- added an example (as Jupyter notebook) for the WikipediaRetriever

Add PDF parser implementations (#4356)
# Add PDF parser implementations

This PR separates the data loading from the parsing for a number of
existing PDF loaders.

Parser tests have been designed to help encourage developers to create a
consistent interface for parsing PDFs.

This interface can be made more consistent in the future by adding
information into the initializer on desired behavior with respect to splitting by
page etc.

This code is expected to be backwards compatible -- with the exception
of a bug fix with pymupdf parser which was returning `bytes` in the page
content rather than strings.

Also changing the lazy parser method of document loader to return an
Iterator rather than Iterable over documents.

Add MimeType based parser (#4376)
# Add MimeType Based Parser

This PR adds a MimeType Based Parser. The parser inspects the mime-type
of the blob it is parsing and based on the mime-type can delegate to the sub
parser.

Update qdrant interface (#3971)
Hello

1) Passing `embedding_function` as a callable seems to be outdated and
the common interface is to pass `Embeddings` instance

2) At the moment `Qdrant.add_texts` is designed to be used with
`embeddings.embed_query`, which is 1) slow 2) causes ambiguity due to 1.
It should be used with `embeddings.embed_documents`

This PR solves both problems and also provides some new tests

[test] Add integration_test for PandasAgent (#4056)
- confirm creation
- confirm functionality with a simple dimension check.

The test now is calling OpenAI API directly, but learning from
@vowelparrot that we’re caching the requests, so that it’s not that
expensive. I also found we’re calling OpenAI api in other integration
tests. Please lmk if there is any concern of real external API calls. I
can alternatively make a fake LLM for this test. Thanks

Update WhatsAppChatLoader regex to handle multiple date-time formats (#4186)
This PR updates the `message_line_regex` used by `WhatsAppChatLoader` to
support different date-time formats used in WhatsApp chat exports;
resolves #4153.

The new regex handles the following input formats:
```terminal
[05.05.23, 15:48:11] James: Hi here
[11/8/21, 9:41:32 AM] User name: Message 123
1/23/23, 3:19 AM - User 2: Bye!
1/23/23, 3:22_AM - User 1: And let me know if anything changes
```

Tests have been added to verify that the loader works correctly with all
formats.

Refactor TelegramChatLoader and FacebookChatLoader classes and add tests (#3863)
This PR includes two main changes:

- Refactor the `TelegramChatLoader` and `FacebookChatLoader` classes by
removing the dependency on pandas and simplifying the message filtering
process.

- Add test cases for the `TelegramChatLoader` and `FacebookChatLoader`
classes. This test ensures that the class correctly loads and processes
the example chat data, providing better test coverage for this
functionality.

Enhancement: option to Get All Tokens with a single Blockchain Document Loader call (#3797)
The Blockchain Document Loader's default behavior is to return 100
tokens at a time which is the Alchemy API limit. The Document Loader
exposes a startToken that can be used for pagination against the API.

This enhancement includes an optional get_all_tokens param (default:
False) which will:

- Iterate over the Alchemy API until it receives all the tokens, and
return the tokens in a single call to the loader.
- Manage all/most tokenId formats (this can be int, hex16 with zero or
all the leading zeros). There aren't constraints as to how smart
contracts can represent this value, but these three are most common.

Note that a contract with 10,000 tokens will issue 100 calls to the
Alchemy API, and could take about a minute, which is why this param will
default to False. But I've been using the doc loader with these
utilities on the side, so figured it might make sense to build them in
for others to use.

[agent][property type] Change allowed_tools to Set as Duplicate doesn’t make sense (#3840)
- ActionAgent has a property called, `allowed_tools`, which is declared
as `List`. It stores all provided tools which is available to use during
agent action.
- This collection shouldn’t allow duplicates. The original datatype List
doesn’t make sense. Each tool should be unique. Even when there are
variants (assuming in the future), it would be named differently in
load_tools.


Test:
- confirm the functionality in an example by initializing an agent with
a list of 2 tools and confirm everything works.
```python3
def test_agent_chain_chat_bot():
	from langchain.agents import load_tools
	from langchain.agents import initialize_agent
	from langchain.agents import AgentType
	from langchain.chat_models import ChatOpenAI
	from langchain.llms import OpenAI
	from langchain.utilities.duckduckgo_search import DuckDuckGoSearchAPIWrapper

	chat = ChatOpenAI(temperature=0)
	llm = OpenAI(temperature=0)
	tools = load_tools(["ddg-search", "llm-math"], llm=llm)

	agent = initialize_agent(tools, chat, agent=AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION, verbose=True)
	agent.run("Who is Olivia Wilde's boyfriend? What is his current age raised to the 0.23 power?")
test_agent_chain_chat_bot()
```

Add unit test to output parsers (#3911)
This pull request adds unit tests for various output parsers
(BooleanOutputParser, CommaSeparatedListOutputParser, and
StructuredOutputParser) to ensure their correct functionality and to
increase code reliability and maintainability. The tests cover both
valid and invalid input cases.

Changes:

Added unit tests for BooleanOutputParser.
Added unit tests for CommaSeparatedListOutputParser.
Added unit tests for StructuredOutputParser.

Testing:

All new unit tests have been executed, and they pass successfully.
The overall test suite has been run, and all tests pass.
Notes:

These tests cover both successful parsing scenarios and error handling
for invalid inputs.
If any new output parsers are added in the future, corresponding unit
tests should also be created to maintain coverage.
