Distribute Rix via Nix

[urbas]

Rix is currently not packaged. Since Rix is all about Nix, it would be sensible to use Nix to package Rix. A nix package definition in flake.nix should do.

If you mean nixpkgs, then it's definitely a bit early for that. They do vet all the programs, and it takes a long time for a PR to get merged in my experience (see NixOS/nixpkgs#292338)

But just doing it in the flake here is easy yeah

Oh, I meant just building the package in our flake. Let me paraphrase this issue.
