Support Snap or Appimage

Anki does not support third party distribution packages :

However, the current distribution method is a terrible way of installing Anki since it comes with a cart of pre-built dependencies and still requires make install.

Please support Snap/Appimage/Flatpak or any other mean of installation.
Theses packaging format are specifically designed for Anki’s usecase, so it is kind of a waste to keep using the archaic make install way.

Long story short, we need a cleaner way of installing Anki.
