Add Huggingface model zoo from community

[matichon-vultureprime]

According to [Feature Request: "Model Zoo" for quantization #1591],
this is our initial effort to create the Model Zoo.
The first model uploaded is Llama3-70b, AWQ Quantized.

I have identified several opportunities within the Model Zoo. I encountered a variety of configurations including PP_size, TP_size, KV_cache_type (fp16, fp8, int8), Group_size (64, 128), and Quantization algorithms (AWQ, SQ, FP8).
I will try to figure out the "proper" base configuration.

I have decided to use the lowest possible Group_size (to prevent the degradation of quantization) and set PP_size to 1.

Let's discuss if we can determine the "proper" configurations.
