Optimal Stepsize for Diffusion Sampling(OSS)- fast flux with 10 sampling steps

[HAMSAILY]

Hello, this is the implementation of the method OptimalSteps, which can accelerate diffusion model sampling significantly, almost without quality loss. The added node "OptimalStepsScheduler" supports the acceleration for text-to-image model FLUX and text-to-video model Wan. Here, we give a demo result of FLUX model with 10 sampling steps
