For Android/Quest development, raise PRs against the android-dev branch.

Outstanding todos:

• Fix color issue
• Fix controller tracking

This PR is to merge it all into master once we're done.

@ChristophHaag @m4gr3d The only thing not working at the moment is finger tracking but we can live without that for now.
It also requires godotengine/godot#51780 to get the correct colors but that has now been approved and will likely be merged.

That does mean we can't release 1.1.0 until Godot 3.4 is out but that will happen soon after Akien returns from holidays.

I suggest we merge this branch into master. I've created a 1.0.x branch for the current version so we can apply patches for fixes to maintain support for Godot 3.3

Let me know what you guys think. I'm planning to start work on the proper Godot 4 port later in the week now that most of the GD extension logic has been merged (the replacement for the old GDNative layer).

Merging into master sounds good!
Is there an issue that tracks the hand tracking bug?
Also, can you give push/write access to the repo.
