Trim Nix binary caches according to GC roots

nix-cache-cut

Yet another garbage collector for Nix binary caches.

This one runs with a list of GC roots just like your ordinary nix-collect-garbage. It does not operate time-based to expire old files like lheckemann's cache-gc.

$ nix run github:astro/nix-cache-cut -- --help
