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 print an error and use the unmodified noise.

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).
