avformat/dashenc: Remove muxer overhead from Bandwidth field in DASH manifest

Muxer overhead calculations was intented for HLS playlist as Apple's mediastreamvalidator tests were failing.

Add FATE test for QT format audio descriptors in MP4

Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

Use QT format for audio sample descriptors depending on stsd version.

ISOBMFF does not allow AudioSampleEntryV1 in stsd version 0, so
assume the descriptor format is QTFF SoundDescriptionV1. ISOBMFF does
not define a version 2.

This fixes audio decoding for some MP4 files generated with Apple
tools. The additional fields present in SoundDescriptionV1/V2 need to
be read in order to correctly read additional boxes that contain
