Add snap package

[leobel96]

I have noticed in another Issue that you planned to make a .deb package. That would be limited to debian-based distros (Ubuntu and so on). I suggest you to create a snap package instead: that would be compatible with almost all linux distros (also Arch, Fedora, CentOs, ...), would be easier to mantain and would auto-update on the user's device.

I honestly have no preference. I guess it would depend on how easy it is to deal with dependencies with snap packages (mainly the openauto and aasdk libraries, I'm sure everything else can be easily dealt with).

I'll have to do so more research into snap packages but its definitely something I wouldn't mind doing.
