ComfyUI custom node for NVIDIA PiD pixel diffusion decoding and upscale workflows

PiD-Image-Upscaler is an experimental, advanced super-resolution and image-to-image refinement application based on the state-of-the-art PiD (Pixel Diffusion Decoder) framework by NVIDIA. This application couples local generative text-to-image and image-to-image pipelines.

Replace VAE decoders with this diffusion module to perform single-pass latent decoding and super-resolution for ComfyUI.
