tests/fake_realsense.py: a pipeline whose wait_for_frames renders a textured
640x480 frameset after 100 ms (no RealSense on the development PC).
tests/test_parallel_capture.py:
- 3 parallel /api/capture take < 2x one alone (medians of 5): the criterion
declared for optimize-streams R01. On the previous code: 391 vs 128 ms.
- /api/capture keeps its fields; parallel requests share one frame and its
bytes, frame_id still differs per response; one thread calls the pipeline.
- /api/rgb, /api/depth, /api/depth/color decode; /ws streams; close() stops
the acquisition thread.
Skipped when pyrealsense2 is not importable, like the existing driver tests.
