Add playback engine with A/V timestamping

Browse Source 
- AnnexBSplitter incrementally splits the Annex-B stream into access
  units, holding partial slices across packet feeds.
- VideoDecoder exposes feedAccessUnit and the decoded frame rate.
- PlaybackEngine demuxes and decodes in lockstep, tagging video frames
  and audio chunks with 90 kHz PTS (audio from PES headers, video from
  PES anchors interpolated by decoder frame rate).
- CLI 'play' command runs the engine headlessly and reports A/V drift.
- Validated against Batman Begins: 95 frames in 4.0s, max drift -78.6 ms
  (video trails audio at stream start), avg frame duration 3833.6 ticks.
- Tests for AnnexBSplitter.
