Mp4 CannotReadException: Unable to determine start of audio in file, fails ungracefully

org.jaudiotagger.audio.exceptions.CannotReadException: Unable to determine start of audio in file (even though file plays and meta-data tags are fine)

Source code throws exception (Mp4AtomTree.java Line 200) documented that the exception is thrown to protect writing to the file later on, however meta-data has been parsed ok and file plays fine. For read-only meta-data projects it would be nice to still be able to get at the data without exception.

Could it be possible to mark the file internally as read-only (and/or log a warning) as the file is still playable and useful meta-data is still extracted for files that suffer from this problem? Some people may only be interested in reading meta-data and not writing to the file like me, For now i have just removed the CannotReadException and returned the dataTree object in Mp4AtomTree.java Line 200 which fixes it for my requirements, but may not be the complete solution.
