Add augmentations for viewpoint shift (camera angle and distance) #16

As in: Contrastive Self-Supervised Learning for Skeleton Action Recognition

Viewpoint Augmentations:

Angle shift
- Implemented as rotation transform of the original coordinate-system
- Currently, the implemented RotationTransform only does rotation about 1 axis. Extend to 2 axis (if possible, 3D)
Distance shift
- (But since we do ScaleNormalization before sending to network, is this necessary?)
- (Also ScaleTransform should handle this?)
