Flatpak package

Could be nice if there is Flatpak package available in Flathub bundling also artyfx.

Just made a prototype that seems to launch Luppp. Will see if I find the time to finish and submit it.

Note that Luppp uses JACK, which in a Flatpak is usually handled by Pipewire. The default setup of distributions various regarding Pipewire: often video support is present, but audio may still be handled by Pulseaudio.
I think MIDI is also going over JACK, so that would need to be handled by Pipewire too (not sure how its state is).

When running the Flatpak, I do see the ports coming up in Pipewire (outside of the Flatpak), but as my system still uses Pulseaudio, I cannot test whether it actually works well.
