/*
Some utility commands:
- `nix flake update --commit-lock-file`
- `nix flake lock update-input <input>`
- `nix build .#dyesub-tool`
- `nix run .#dyesub-tool`

Updating `cargoHash`:
- Set `cargoHash` to an empty string
- run `nix run .#dyesub-tool`
- Update `cargoHash` with correct hash from output
