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 information required for decoding the stream. Fixes #7376.
