Urs FleischandGitHub 2a5fc12b68 Support additional MP4 codecs (#1293, #1338) ...

Adds MP4::Properties::Codec enum values AC3, EAC3, FLAC, DTS, Opus and a
MP4::Properties::codecId() method.
Parse high-res FLAC bitrate from MP4 dfLa box.
Parse E-AC-3 bitrate from MP4 dec3 box.

The test files were generated using ffmpeg:
