Automatic issue filing / flatbuffer upload/download

[nsmithtt]

We have an existing offline tool ttrt for working with flatbuffers. Let's add GitHub API support for supporting file upload of a flatbuffer to GitHub.

For e.g.

# Upload 
ttrt upload --issue 44 out.ttnn
# Download 
ttrt download --issue 44 out.ttnn

Behind the scenes the ttrt script zips the flatbuffer and uses GitHub API to post the artifact to the issue.

Notes:

• We must zip the file and ensure the file extension ends with .zip otherwise GitHub will reject, for this we can use: https://docs.python.org/3/library/zipfile.html
• Let's try to first see if we can use builtin python3 library urllib: https://docs.python.org/3/library/urllib.request.html#module-urllib.request
• Let's try not to use any additional python deps
• The runtime python tools live here: runtime/tools/python, let's create a new submodule ttrt/upload.py
• Inside of ttrt/__init__.py we can create new subcommands upload and download

If this works, as a follow on task we can add support for creating new issues from a failing flatbuffer.

A little bit of light googling, it seems like this isn't officially supported by GitHub API, let's investigate and see what options we have available to us. We could store the files on S3 and post links to them, or store in an LFS repo or something, not sure.

Added basic functionality for upload, download and create with GitHub issues using a public repo I created. Can transfer this over to this repo when it is opened up. Still need to mock up a fileserver and do the actual upload/download of the flat buffer file
