Create AUR package

[anaisbetts]

It would be cool to create an -bin AUR package of this repository, it would make installation/uninstallation a bit cleaner and would mean that updates could be streamlined vs having to manually run the installer script to update. It looks like a lot of the pieces are already here to make a decent PKGBUILD file

It would be easy to create a source-based package too but that would mean you'd have to require that base-devel (or at least clang) would be on the Steam Deck which might pull in too many dependencies
