Generalization of the merging operation #121

Hi @zhengkw18 @jt-zhang Thanks for your great efforts!

Regarding turbodiffusion/scripts/merge_models.py, could it be employed as a common practice of merging step distillation weights (e.g., DMD, discrete / continuous CD, adversarial distillation, etc.) and sparse attn weights (e.g., VSA, STA, radial attn, etc.), in order to combine their strength?

Or else, it is just a nice property of rCM together with SLA? Thanks in advance.
