Some mpeg versions use LSF (low sampling frequency) when encoding
low sample rates which changes a bit how the side info is layed out.
Also skip trying to separate data and other_data as after reading up
a bit on how main data begin and bit reservoir works i think it was done
incorrectly. To know the real audio data length i think you need to decode
the huffman tables. Instead just have a "audio_data" field which are the
bits with audo data for current and possibly following frames.
Will produce one field per sample which is a bit too much.
Maybe in some future fq can have smart array types that could handle this better.
Also add data_format per track to make it easier to understand things.
Fragmened mp4s can have no tkhd box or tkhd box with a track_id that does not match
any tfhd box track_id. Make is possible to see samples for these fragmented tracks
ny adding tracks for unseen track_ids.
Also add id field for tracks.
mp3: Remove one level of struct for granales
dump: Makes it a bit easier to understand array of arrays/structs.
avro_ocf: Rename ocf.go -> avro_ocr.go to have same name of source file as format
pcap,pcapng: Rename tcp flow struct to tcp_connection, makes more sense i think
mp4: Add ISOBMFF to format description
