Cache and determine packages installed on legacy NixOS and with nix-env

Functions

getenvpkgs

Gets a list of all packages installed with nix-env with their name and version. Due to limitations of nix-env, the HashMap keys are the packages pname rather than attributePath. This means that finding more information about the specific derivations is more difficult.

getlegacypkgs

Gets a list of all packages in NixOS systems with their attribute and version. The input paths should be the paths to the configuration.nix files containing environment.systemPackages

legacypkgs

Gets a list of all packages in legacy NixOS systems with their name and version. Can be used to find what versions of system packages are currently installed. Will only work on legacy NixOS systems.
