turns out i use nixos now so this will make the development process
wayyyy easier for me
you can now build linutil for nix with `nix build`, enter the dev
environment with `nix develop`, and format nix code with `nix fmt`
and if some crazy person was to use linutil on nixos, now they can with
`nix run github:ChrisTitusTech/linutil` or by adding linutil to their
flake
