[Documentation] Show how to initiate pinecone from an existing index (#3070)
## What is this PR for:
* This PR adds a commented line of code in the documentation that shows
how someone can use the Pinecone client with an already existing
Pinecone index
* The documentation currently only shows how to create a pinecone index
from langchain documents but not how to load one that already exists

Generative Characters (#2859)
Add a time-weighted memory retriever and a notebook that approximates a
Generative Agent from https://arxiv.org/pdf/2304.03442.pdf


The "daily plan" components are removed for now since they are less
useful without a virtual world, but the memory is an interesting
component to build off.

Add an example tutorial for using PDFMinerPDFasHTMLLoader (#2960)
Last week I added the `PDFMinerPDFasHTMLLoader`. I am adding some
example code in the notebook to serve as a tutorial for how that loader
can be used to create snippets of a pdf that are structured within
sections. All the other loaders only provide the `Document` objects
segmented by pages but that's pretty loose given the amount of other
metadata that can be extracted.

With the new loader, one can leverage font-size of the text to decide
when a new sections starts and can segment the text more semantically as
shown in the tutorial notebook. The cell shows that we are able to find
the content of entire section under **Related Work** for the example pdf
which is spread across 2 pages and hence is stored as two separate
documents by other loaders

SVM retriever (#2947) (#2949)
Add SVM retriever class, based on
https://github.com/karpathy/randomfun/blob/master/knn_vs_svm.ipynb.

Testing still WIP, but the logic is correct (I have a local
implementation outside of Langchain working).

[minor] Deep Lake auth improvements in docs, kwargs pass, faster tests (#2927)
Minor cosmetic changes 
- Activeloop environment cred authentication in notebooks with
`getpass.getpass` (instead of CLI which not always works)
- much faster tests with Deep Lake pytest mode on 
- Deep Lake kwargs pass

Notes
- I put pytest environment creds inside `vectorstores/conftest.py`, but
feel free to suggest a better location. For context, if I put in
`test_deeplake.py`, `ruff` doesn't let me to set them before import
deeplake

Add file filter param to Git loader (#2904)
Allows users to specify what files should be loaded instead of
indiscriminately loading the entire repo.

extends #2851 

NOTE: for reviewers, `hide whitespace` option recommended since I
changed the indentation of an if-block to use `continue` instead so it
looks less like a Christmas tree :)

Add Slack Directory Loader (#2841)
Fixes linting issue from #2835 

Adds a loader for Slack Exports which can be a very valuable source of
knowledge to use for internal QA bots and other use cases.

```py
# Export data from your Slack Workspace first.
from langchain.document_loaders import SLackDirectoryLoader

SLACK_WORKSPACE_URL = "https://awesome.slack.com"

loader = ("Slack_Exports", SLACK_WORKSPACE_URL)
docs = loader.load()
```

WhatsApp document loader - update regex (#2776)
I was testing out the WhatsApp Document loader, and noticed that
sometimes the date is of the following format (notice the additional
underscore):
```
3/24/23, 1:54_PM - +91 99999 99999 joined using this group's invite link
3/24/23, 6:29_PM - +91 99999 99999: When are we starting then?
```

Wierdly, the underscore is visible in Vim, but not on editors like
VSCode. I presume it is some unusual character/line terminator.
Nevertheless, I think handling this edge case will make the document
loader more robust.

loader = BiliBiliLoader(
       ["https://www.bilibili.com/video/BV1xt411o7Xu/",
       "https://www.bilibili.com/video/av330407025/"]

Add new loader to load pdf as html content (#2607)
Adds a new pdf loader using the existing dependency on PDFMiner. 

The new loader can be helpful for chunking texts semantically into
sections as the output html content can be parsed via `BeautifulSoup` to
get more structured and rich information about font size, page numbers,
pdf headers/footers, etc. which may not be available otherwise with
other pdf loaders

Deep Lake retriever example analyzing Twitter the-algorithm source code (#2602)
Improvements to Deep Lake Vector Store
- much faster view loading of embeddings after filters with
`fetch_chunks=True`
- 2x faster ingestion
- use np.float32 for embeddings to save 2x storage, LZ4 compression for
text and metadata storage (saves up to 4x storage for text data)
- user defined functions as filters

Docs
- Added retriever full example for analyzing twitter the-algorithm
source code with GPT4
- Added a use case for code analysis (please let us know your thoughts
how we can improve it)

Qdrant update to 1.1.1 & docs polishing (#2388)
This PR updates Qdrant to 1.1.1 and introduces local mode, so there is
no need to spin up the Qdrant server. By that occasion, the Qdrant
example notebooks also got updated, covering more cases and answering
some commonly asked questions. All the Qdrant's integration tests were
switched to local mode, so no Docker container is required to launch
them.

Introduces SeleniumURLLoader for JavaScript-Dependent Web Page Data Retrieval (#2291)
### Summary
This PR introduces a `SeleniumURLLoader` which, similar to
`UnstructuredURLLoader`, loads data from URLs. However, it utilizes
`selenium` to fetch page content, enabling it to work with
JavaScript-rendered pages. The `unstructured` library is also employed
for loading the HTML content.

### Testing
```bash
pip install selenium
pip install unstructured
```

```python
from langchain.document_loaders import SeleniumURLLoader

urls = [
    "https://www.youtube.com/watch?v=dQw4w9WgXcQ",
    "https://goo.gl/maps/NDSHwePEyaHMFGwh8"
]

loader = SeleniumURLLoader(urls=urls)
data = loader.load()
