[Feature Request] Add test animated loop Adapter (aka dummy tracker)

[grillo-delmal]

The idea is to add an adapter that loops Bones and Blendshape messages to simulate tracking reception. This would be useful for testing rigs without needing to connect a camera or any special tracker.

Ideally to have a single loop to test with would be enough, but having multiple animations or being able to import them from a file would be ideal :)
