What's Changed

⚡ Offload tokenizer fixes to Toke(n)icer pkg.
⚡ Optimized lm_head quant time and vram usage.
⚡ Optimized DeekSeek v3/R1 model quant vram usage.
⚡ 3x speed-up for Torch kernel when using Pytorch >= 2.5.0 with model.compile().
⚡ New calibration_dataset_concat_size option to enable calibration data concat mode to mimic original GPTQ data packing strategy which may improve quant speed and accuracy for datasets like wikitext2.
