Better packaging

[marzipankaiser]

Package the script to be easily usable in major distributions and nixos.

[marzipankaiser]

NixOS should be possible with #12 by importing default.nix (which then fetches the version on the Github master(!) ). This is not ideal but should mostly work.

Improved NixOS Packaging in #21

[marzipankaiser]

PRs for other distributions are welcome.

[marzipankaiser]

PKGBUILD for Archlinux in #40.

[marzipankaiser]

Packaging is now reworked, see #42, #43, and some direct pushes to master (sry, this did not go as intended...)
There is now a Makefile able to build some packages in a packages subdirectory.

[marzipankaiser]

#47 will soon bring a CI/CD to automatically build release packages.

[marzipankaiser]

The NUR package in marzipankaiser/nur-packages is now automatically updated by the CI since #56.
