Support multiple `trun` boxes in a single `traf` box #135

Closed jerzywilczek closed 6 months ago

MPEG-4 part 12 section 8.8.8 states that a traf box may contain multiple trun boxes. This patch allows parsing such files correctly. Previously, the library would only parse the last trun box for each traf box, which caused the tracks to be unplayable.

Closing, since upon further inspection I am no longer sure that my changes are entirely correct.
