from_coding_type maps 0x20 (MVC dependent view) to Codec::H264, so the existing PAT/PMT scan surfaces the SSIF right-eye substream as a second video stream on its own PID instead of dropping it as Unknown. No new parser: the dependent eye rides the same demux path as any other TS video stream. Removes the throwaway 3D-structure probes (findings captured in prior commit messages).
