Feature Request - create and publish flatpak

[loganb-aja]

I would be really nice to have a flatpak of this app available on flathub for distribution.

This would help with exposure of this project and also provide a distribution agnostic method for installing that doesn't require building from source.

Here's a link to the flatpak build documentation... https://docs.flatpak.org/en/latest/building.html

Once a build is created and tested, here's how to publish the flatpak to the flathub repo... https://docs.flathub.org/docs/for-app-authors/submission/

Thanks!
