Use loguru, not logging module

[horheynm]

Convert from logging module to loguru.
Loguru deps dont have conflict or adds any ML-specific libraries that will collide.

Nice. This adds loguru as a dependency to vllm, so we should briefly verify that vllm + this branch of CT does not have any dependency conflicts.

We should probably bound the version of loguru to prevent against upstream vulnerabilities

[horheynm]

Ok good point. loguru is helpful on our side, but this repo is for vllm inference.
I can map which part of vllm uses what part of compressed_tensors. but its best not to add extra dependencies.
vllm doesnt use loguru

Ill close this for now
