feat(dec3): parse JOC extension for Dolby Atmos detection

To detect Dolby Atmos, parse the JOC (Joint Object Coding) extension from the EC3SpecificBox
(dec3) per ETSI TS 103 420 C.3.1 by extracting `flag_ec3_extention_type_a` and `complexity_index_type_a` from trailing bytes after EC-3 substream entries, which is compatible to ETSI TS 102 366 F.6
