cmdr2's notes

Spent the last week or two getting torchruntime fully integrated into Easy Diffusion, and making sure that it handles all the edge-cases.

Easy Diffusion now uses torchruntime to automatically install the best-possible version of torch (on the users' computer) and support a wider variety of GPUs (as well as older GPUs). And it uses a GPU-agnostic device API, so Easy Diffusion will automatically support additional GPUs when they are supported by torchruntime.

This also makes it easier for developers to add support for more (or newer) GPUs in a simpler code base (i.e. torchruntime), instead of digging into the internals of Easy Diffusion's codebase.

This removes a lot of custom, hacky code from Easy Diffusion for installing torch. This hacky code was the initial source of knowledge for torchruntime, and I'm thankful to all the contributors who poured their knowledge into it.
