Hires fix right after the img2img process, using its latent.
Inspired by wcde/custom-hires-fix-for-automatic1111, which has been archived and isn't functioning since 2023.
Simple 150 lines extension with minimized features and dependency.
It also works in txt2img, you can check the consistency between the Original "Hires. fix" and this extension.
I made this because I need this feature🤣
(Originally, if you upscale using/before img2img, the anatomy will be broken at higher resolution.)
