- Add bbox_depth_center position strategy in SceneGraphBuilder using depth
at bbox centre and configurable camera_hfov_degrees for pinhole projection.
- Add optional depth_sensor_uuid to HabitatSimulatorConfig; create depth
sensor spec alongside RGB sensor.
- Add camera_position/camera_rotation fields to RoomView; capture pose from
sensor_states when depth sensor is available.
- Update flatten_room_views for backward compatibility with legacy tuple
format.
- Wired in depth sensor and bbox_depth_center strategy in verification
notebook.
- Add tests for depth sensor support and new position strategies.
