SCTE-35 passthrough to MP4 [bounty]

[Mista_D]

Looking for SCTE-35 pass through implementation:

1. Extract SCTE-35 from MPEG-TS.
2. Translate timing of the original SCTE-35 events to match timing in the output file appropriately or keep timing as is.
3. Signal encoder to force key frames at the boundaries of the SCTE-35 event.
4. Inject SCTE-35 messaging into output MP4 files as emsg and into MPD and M3U8 manifests if/as needed.
