Huggingface bot

[rchan26]

• Update Hugs to be able to use OpenAI API if MODEL_NAME == "gpt-3.5-turbo" (i.e. calls API rather than performing inference with model loaded from transformers)
• Also add work from Day 2 on load larger models from transformers and using bitsandbytes
• Few updates to poetry.lock and pyproject.toml
