Framework for supporting more languages in LanguageParser (#13318)
## Description

I am submitting this for a school project as part of a team of 5. Other
team members are @LeilaChr, @maazh10, @Megabear137, @jelalalamy. This PR
also has contributions from community members @Harrolee and @Mario928.

Initial context is in the issue we opened (#11229).

This pull request adds:

- Generic framework for expanding the languages that `LanguageParser`
can handle, using the
[tree-sitter](https://github.com/tree-sitter/py-tree-sitter#py-tree-sitter)
parsing library and existing language-specific parsers written for it
- Support for the following additional languages in `LanguageParser`:
  - C
  - C++
  - C#
  - Go
- Java (contributed by @Mario928
https://github.com/ThatsJustCheesy/langchain/pull/2)
  - Kotlin
  - Lua
  - Perl
  - Ruby
  - Rust
  - Scala
- TypeScript (contributed by @Harrolee
https://github.com/ThatsJustCheesy/langchain/pull/1)

Here is the [design
document](https://docs.google.com/document/d/17dB14cKCWAaiTeSeBtxHpoVPGKrsPye8W0o_WClz2kk)
if curious, but no need to read it.

## Issues

- Closes #11229
- Closes #10996
- Closes #8405

## Dependencies

`tree_sitter` and `tree_sitter_languages` on PyPI. We have tried to add
these as optional dependencies.

## Documentation

We have updated the list of supported languages, and also added a
section to `source_code.ipynb` detailing how to add support for
additional languages using our framework.

## Maintainer

- @hwchase17 (previously reviewed
https://github.com/langchain-ai/langchain/pull/6486)

Thanks!!

## Git commits

We will gladly squash any/all of our commits (esp merge commits) if
necessary. Let us know if this is desirable, or if you will be
squash-merging anyway.

docs: add use case for managing chat messages via Apache Kafka (#16771)
Adding a new notebook that demonstrates how to use LangChain's standard
chat features while passing the chat messages back and forth via Apache
Kafka.

This goal is to simulate an architecture where the chat front end and
the LLM are running as separate services that need to communicate with
one another over an internal nework.

It's an alternative to typical pattern of requesting a reponse from the
model via a REST API (there's more info on why you would want to do this
at the end of the notebook).

NOTE: Assuming "uses cases" is the right place for this but feel free to
propose another location.

community[patch]: Fixed the 'aembed' method of 'CohereEmbeddings'. (#16497)
**Description:**
- The existing code was trying to find a `.embeddings` property on the
`Coroutine` returned by calling `cohere.async_client.embed`.
- Instead, the `.embeddings` property is present on the value returned
by the `Coroutine`.
- Also, it seems that the original cohere client expects a value of
`max_retries` to not be `None`. Hence, setting the default value of
`max_retries` to `3`.

community[minor], langchian[minor]: Add Neptune Rdf graph and chain (#16650)
**Description**: This PR adds a chain for Amazon Neptune graph database
RDF format. It complements the existing Neptune Cypher chain. The PR
also includes a Neptune RDF graph class to connect to, introspect, and
query a Neptune RDF graph database from the chain. A sample notebook is
provided under docs that demonstrates the overall effect: invoking the
chain to make natural language queries against Neptune using an LLM.

**Issue**: This is a new feature
 
**Dependencies**: The RDF graph class depends on the AWS boto3 library
if using IAM authentication to connect to the Neptune database.

I'm not sure `libs/langchain` is the right place for this change. At
first, I wanted to put it under `libs/community`. All the compressors
were under `libs/langchain/retrievers/document_compressors` though. Hope
this makes sense!

[TO-BE] In the absence of extension length constraints in the OS, the
extension of the YAML file is yaml, but control over the yml extension
must still be made.

It's as if it's an error because it's a .jpg extension in jpeg support.

community[patch]: Fix github search issues and PRs PaginatedList has no len() error (#16806)
**Description:** 
Bugfix: Langchain_community's GitHub Api wrapper throws a TypeError when
searching for issues and/or PRs (the `search_issues_and_prs` method).
This is because PyGithub's PageinatedList type does not support the
len() method. See https://github.com/PyGithub/PyGithub/issues/1476

  **Dependencies:** None 
  **Twitter handle**: @ChrisKeoghNZ
  
I haven't registered an issue as it would take me longer to fill the
template out than to make the fix, but I'm happy to if that's deemed
essential.

I've added a simple integration test to cover this as there were no
existing unit tests and it was going to be tricky to set them up.

core[patch]: Replace memory stream implementation used by LogStreamCallbackHandler (#17185)
This PR replaces the memory stream implementation used by the 
LogStreamCallbackHandler.

This implementation resolves an issue in which streamed logs and
streamed events originating from sync code would arrive only after the
entire sync code would finish execution (rather than arriving in real
time as they're generated).

One example is if trying to stream tokens from an llm within a tool. If
the tool was an async tool, but the llm was invoked via stream (sync
variant) rather than astream (async variant), then the tokens would fail
to stream in real time and would all arrived bunched up after the tool
invocation completed.
