Bug: Outlier Split Index Error
The outlier_split method risks an IndexError. The lower_cutoff_idx calculation can produce an index such that lower_cutoff_idx + 1 exceeds self.n - 1, leading to out-of-bounds access on sorted_W for small self.n or certain ratio values.

Bug: Quantizer Configuration System Broken
The gpt.fasterquant() method uses hardcoded default values for quantization parameters like weight_bits, max_epoch, and pre_process. The lines meant to pass these user-configured hyperparameters from smash_config are commented out, which makes the quantizer's configuration system non-functional.

Description
This PR adds the GANQ quantizer.
Related Issue
Fixes #391
Type of Change
How Has This Been Tested?
I have locally tested that the GANQ quantization works, however a lot of things need to be discussed with the team to write more formal tests. Will add.
Checklist
Additional Notes
This quantizer is not fully ready yet, I am creating a PR to get early feedback.
I will be fixing the issues I am getting with the pre-commit(like variable names, docstrings etc) soon. Some of those are failing and I had to use
--no-verify
