6df4e78d96 Remove non-relative Seek calls from all functions. 
Previously we would seek to the beginning of the io.ReadSeeker. It is much more
flexible to assume that the caller passes the ReadSeeker in an appropriate state.

be3da62488 Add more tags to mp4 
1) correct a bug with the mdat atom.
Sometimes, the metadata can be at the end, after the audio
Demo :
   get any music file and strip the metadata
   convert it to m4a with ffmpeg
   analyse it with MusicBrainz Picard
   et voila, you have the metadata at the end.

Example of structure of a m4a created that way;
https://www.dropbox.com/s/602yivdstan7506/atom.txt?dl=0

2) add support for the "----" tag
See http://atomicparsley.sourceforge.net/mpeg-4files.html
It gives access to the tags created by MusicBrainz Picard
