Flake for running SD on NixOS

What's done

• Nix devShell capable of running InvokeAI's flavor of SD without need to fallback for pip or conda (targets AMD ROCM)
• ...???
• PROFIT

How to use it?

1. Clone repo
2. Clone submodule with InvokeAI
3. Run nix develop, wait for shell to build
4. Inside InvokeAI's directory, run python scripts/preload_models.py to preload models
5. Place SD weights into models/ldm/stable-diffusion-v1/model.ckpt
6. Run CLI with python scripts/invoke.py or GUI with python scripts/invoke.py --web
7. For more detailed instructions consult https://invoke-ai.github.io/InvokeAI/installation/INSTALL_LINUX/

What's needed to be done

• devShell with CUDA support (should be trivial, but requires volunteer with NVidia GPU)
• Missing packages definitions should be submitted to Nixpkgs
• Investigate ROCM device warning on startup
• Apply patches so that all downloaded models would go into one specific folder
• Should create a PR to pynixify with "skip-errors mode" so that no ugly patches would be necessary
• Shell hooks for initial setup?
• May be this devShell should be itself turned into a package?
• Add additional flavors of SD ?
