What should this feature add?

spandrel is a module extracted from the chaiNNer project that facilitates loading and running ML models. The focus is on image restoration workflows. Many architectures are supported. A1111 uses this in some fashion.

We should explore leveraging this library to extend our upscaling capabilities.

@RyanJDick Any thoughts on relying on spandrel for upscaling? Maybe this can be a solid base for our upcoming upscaling sprint.
