olympus: init at 24.12.28.01

This is an attempt to package [Olympus](https://everestapi.github.io/), a GUI for installing Everest and managing Celeste mods.
This is based on this [draft](NixOS#295258), with the authors permission.

It maintains the previous issue of not being able to launch Steam
versions of Celeste from the command line but that's not feasible
without upstream changes.

I only have to note that it has a popup complaining about
finishing the installation but that's due to xdg-mime
x-scheme-handler/everest not being set.

Finally I want to note that it depends on lua51Packages.nfd, which
is broken while [this](NixOS#309026)
isn't merged so currently has the fix there.

Finally, [Lönn](https://github.com/CelestialCartographers/Loenn) works
as expected, being the installation managed by the program.

Ahorn is deprecated(in favor of Loenn) and it crashes over trying to run dynamic
executables
