Subject: [PATCH] remove nix support (#47)

Nix is not supposed to be used on NixOS the way that cpm implements it,
and it's (to the best of my knowledge) not the best way on other
platforms as well. We also do not support non-platform-specific package
managers, so the precedent says we should remove this one.
