One finger rotate

[JohanAlbrectsen]

New Feature

It would be really cool, if when panEnabled=false (disabled panning the map), that rotating the map could somehow be done with one finger (currently requires two fingers in all cases). A property: enableSingleFingerRotateWhenPanDisabled could be added to the GestureOptions model.

Why

This would allow for pokemon-go like Apps to be made using MapBox. Would be insanely cool! And it doesn't seem like a feature that's very difficult to build. Kind regards :)
