Differentiating emerge package counts by set (@world, @system, deps)

[hydrospherics]

Just a question for the maintainer and anyone out here: currently, fastfetch reports all emerge packages as a single count, conflating @world, @system, and pulled-in dependencies. Poor Portage getting discriminated while nixpkgs gets first-class treatment..

As per the Gentoo Wiki on Package Sets, @system and @profile are "defined by the Gentoo development team" as the base set of packages required for the OS to function, so essentially system-level metadata.

Since fastfetch already differentiates nix-system and nix-user, Portage deserves the same parity. Calculating these essentially costs nothing, it's just reading /var/lib/portage/world and the profile's packages file.

Counts would be mutually exclusive: total - (@world + @system) = deps. Two formats on the table:

1:

packages: 76 (@world), 50 (@system), 919 (emerge-deps), 12 (flatpak)

2 (much like nix-system/nix-user):

packages: 76 (emerge-world), 50 (emerge-system), 919 (emerge-deps), 12 (flatpak)

or whichever you guys prefer, I'll try and see.

just to add, I'm the one implementing, just asking a question before I go on and do the work
