### Rotation filter

The rotation filter transforms depth and IR frames by rotating them by specified angles: 0°, 90°, 180°, and -90°.
This allows re-orienting frames to fit the required perspective for various applications.

After the resulted frame is produced, the frame intrinsic parameters are recalculated to account for rotation.

## Design and Implementation
Post-processing modules are encapsulated into self-contained processing blocks, that provide for the following key requirements:
1. Synchronous/Asynchronous invocation
