Feature Req: Flatpak and/or appimage for Linux

[My1]

Currently, judging by the Readme, the only Linux version offered is snap, which is kinda *buntu/Canonical-centric and maybe should not be the only format available, at least in my opinion, having more open and/or universal formats would be very useful for users of various distributions and alignments.

This is GUI apps, for Headless use Nginx or docker.
