Training-free acceleration for Mochi

[LiewFeng]

Hi, thank you for your awesome work in Mochi. TeaCache can speedup Mochi 2x without much visual quality degradation, in a training-free manner. Welcome to have a try!

I would also like to take this opportunity to recommend SageAttention, which can achieve 2x lossless end-to-end video generation acceleration.

Thanks for the recommendation @LiewFeng. I'll take a look at TeaCache, and see if it's easy to integrate. @jt-zhang We already use SageAttention, but I do see that SageAttention2 is coming out, which we should give a spin as well.
