ComfyUI NPNet

A very barebones copypaste implementation of https://github.com/xie-lab-ml/Golden-Noise-for-Diffusion-Models

Note: only works with square noise, apparently. If you pass in other shaped latents, it will reshape the noise into a square before running the noise model, and then reshape the result back to the original resolution.

Use with custom sampling and pass in an initial noise from eg. RandomNoise and a cond (only the first prompt in the conditioning will be used if multiple exist).
