Subject: Add rotation smoothing to Camera2D

Camera2D has follow smoothing to interpolate towards a target position, but no rotation smoothing to align with the target rotation.

This adds rotation smoothing directly into the Camera2D API by having two new properties:
  - `rotation_smoothing_enabled`
  - `rotation_smoothing_speed`
