Add Sober to the AUR

[kaffyfr]

I was wondering if there are any plans to add Sober to the AUR. I personally dislike using Flatpak and I would appreciate if you guys can add Sober to the AUR or even just make an appimage.

I think it would be easier to inject into the game if it was on AUR, since its in flatpak, there is the flatpak environment which somewhat protects it from injections / cheating
