Add a mobile version

[mwestphal]

Context
F3D is a tool that let user visualize 3D models easily. Having a mobile android version would be benificial for the project.
A simple idea would be able to support opening a file attached to an email. iOS version could be considered as well.

Current status
@Meakk has created a prototype of an android app that rely on the libf3d: https://github.com/f3d-app/f3d-android

Some non-exhaustive related tasks

• Migrate to Kotlin
• Improve zoom and pan interaction (it jitters, there must be something wrong)
• Create CI to generate one .apk per architecture
• Add an hamburger menu to toggle some options (e.g. grid)

And provide the .apk files as a release (additionally or instead of putting it into google play).
