wyrde branch sharpen HR-Fix model upscaling x4 (many images)

Takes an image from text prompt (or image) and

• samples it

• uses an upscale model on it

• reduces it again and sends to a pair of samplers

• they upscale and reduce

• then send results to another pair of samplers

Not quite a true double-pass sharpen, but the results are decent. Lots of variation.

Unhook noodles or mute nodes to reduce undesired images and paths. Move noodles to switch VAE and img2img.
