Flux+ControlNet-Upscaler image reverse upsampling

Flux combined with the controlnet-upscaler model amplifies better than sd-upscaler and other methods, enhancing details and maintaining consistency with the original image to the maximum extent.

Added reverse push keyword feature, which can be turned on with one click.

The default model is the new flux distillation 4-step image output model, with original nodes and configurations more suitable for hand-drawn game styles, and of course also suitable for other realistic anime styles, universally usable without adjustments.
