Creating an initial Quantization Directory (#863)

* Initial Creation of a quantization directory

* Moving qops

* updating import

* Updating lm_eval version (#865)

Fixing CI related to EleutherAI/wikitext_document_level change requirements from using HF Datasets

* Pinning numpy to under 2.0 (#867)

* Update Quant call using llama.cpp (#868)

llama.cpp did a BC breaking refactor: ggml-org/llama.cpp@1c641e6
resulting in some of our CI breaking

This updates our CI to match llama.cpp's schema

* Updating torch nightly to pick up aoti improvements in 128339 (#862)

* Updating torch nightly to pick up aoti improvements in 128339

* Update the torch version to 2.5

* Updating lm_eval version (#865)

Fixing CI related to EleutherAI/wikitext_document_level change requirements from using HF Datasets

* Pinning numpy to under 2.0 (#867)

 ## Examples
 We can mix and match weight quantization with embedding quantization.
