The fake frames now hand out a buffer (memoryview) like pyrealsense2's
BufData, so np.asanyarray() of it is a view, as on the robot; a control test
proves it. Then: the captured rgb/depth share no memory with the fake SDK
frame and own their data (without the fix both shared it), and _owned()
copies views only.
