OpenAI RAG Chat With GitHub Topic

This prototype contains:

• rendergit-topic.py: Takes a GitHub Topic as a CLI argument and calls rendergit on each repo - turning each repo into a potentially large (>100MB) HTML file.
• openai-file-search.py: Creates a RAG index of all of these files using OpenAI. This can take a substantial amount of time for a large topic.
• rag-chat-multi.py: A familiar Streamlit chatbot UI. Automatically connects to an OpenAI file search (RAG) ID if available. Supports file uploads, specification of the API key and model selection. Has some quirks.
