Integrate SVDQuant for efficient inference.

[alethea-deepak]

SVDQuant is a quantization technique developed by MIT HAN Lab team for maintaining high quality results even with 4-bit precision diffusion models and have demonstrated its effectiveness with various models.

It would be great additions to this repo.

Thank you for your suggestion. We noticed this acceleration technology a few months ago and had discussions about it. The development of SVDQuant is still ongoing, and we will decide on its integration into this project based on the progress of its development.
