Implement module for home-manager

[Lehmanator]

Without a module for home-manager, I am unable to fully replace sops-nix (or agenix) with secrix.

Would be nice if there was a flake output: homeManagerModules.secrix that defined options similar to secrix.system, but for individual users under a name like secrix.users.<name>.

Some implementation ideas beyond just renaming options & adapting their config implementations to home-manager:

• Option(s) to toggle fallback to using system secrets with the same name if missing for the user. (e.g. I normally use nixos-rebuild
  • Fallback for all secrets: secrix.users.fooAdmin.enableSystemFallback = true
  • Fallback for individual secrets: secrix.users.fooAdmin.secrets.<name>.enableSystemFallback=true (or set value to a (list of) string(s) with secret name(s))

Apologies for the delay!

Allowing this to work with home-manger has certainly been on my slate. I'm hoping to have that done soon. For now, my suggestion would be to add a system secret with proper permissions, then pass it into home manager via osConfig. It's certainly not ideal, but very well may work as a stop gap.

enableSystemFallback is an interesting idea, and likely won't make it to the first iteration, but I like the idea. I'll see what I can do with it.

Would love this as well 👍🏽 My use case only involves user secrets, so a HM module would be ideal 🥹
