Supported Model in README

[sanjeev-bhandari]

Can you please update the README, specifying which model do you support? All LLMs from the hugging face Or specific architecture?
If not will you support other model in future?

Extended from this issue: #30

By the way, this is great library for quantizing model.

Hi, I think it's quite clear.
If a Hugging Face model is not on the list (llama, Mistral, Mixtral, Phi), use auto mode: https://github.com/mobiusml/hqq/?tab=readme-ov-file#auto-mode-1
Auto-mode basically tries to figure out how to quantize stuff automatically, but it's not guaranteed to work.
