feat: Parse MPEG-TS PMT ES language and maximum bitrate descriptors (#369) #1311

Part of https://github.com/shaka-project/shaka-packager/issues/369

This adds read support for some MPEG-TS PMT elementary stream descriptors:

ISO639 Language Descriptor providing language code and audio type
Maximum Bitrate Descriptor providing peak stream bandwidth

Those metadata are propagated to StreamInfo structures:

StreamInfo.language field
AudioStreamMetadata.max_bitrate field for audio streams
audio type is currently not propagated - corresponding field has to be added to AudioStreamMetadata

Test vector file containing those descriptors is provided.
