This still has an issue, because tests cannot run with network inside of
the flake.
When this is solved, the code just needs to be refactored and it's
ready.

The flake is still not fully functional.
First, it seems nescesarry to get a solid system for relative paths,
so that we can run tests inside of a nix build.
To iterate on this, use `nix flake check`.
