Snap packaging

**Is your feature request related to a problem? Please describe.**

AntiMicroX isn't available (for now, at least) on Ubuntu official repositories (original AntiMicro still is) so I have to download and install the official Debian package for each release and reinstall.

**Describe the solution you'd like**
Would be a nice idea to have AntiMicroX packaged as a Snap together with Flatpak. Snaps support multiple distros and are easy to install and update automatically (almost like a Debian package).

**Describe alternatives you've considered**
Add the package do Debian repository and eventually Ubuntu (my distro of choice) will import the packages, but may be take more than just one release to do that.
