Clean up Nix Flake and packaging (#24)

* refactor(nix): split package.nix from flake.nix

* chore(nix): split checks; add more

* ci: run all nix checks

* ci: build in debug mode

* chore(nix): use versionCheckHook

this makes sure the version test is always run, and on the right package

* chore(nix): nix-filter -> lib.fileset

* feat(nix): support stable nix

* ci: fix clippy check
