look at `flake-parts`as kind of framework to manage my flakes as system conf

I recently switched to flake-parts as kind of framework to manage my flakes, roughly as if they were configuration.

Therefore this flake currently still contains a lot of quick legacy stuff for easier migration. Basically everything you see here in the second code block is such legacy code.

The interesting part is the home_configs.nix and system_config,nix which define "options" that make it easier to create actual nixos and HM configurations as required by the respectve tooling.

Both modules are written in a way, that they follow a strict convention but make it easily possible to override specifics if necessary.
