This is the code to load the model and inference it with only a text
prompt. This commit does not contain the nodes to properly use it with an
image input.

This supports both the original SD1 instructpix2pix model and the
diffusers SDXL one.

Use the UNET Loader node to load the unet file to use them.

Improve diffusers model detection.

Large refactor of the model detection and loading code.
