This currently only works for the case where the components are stored in playback order in the file. Set some more default/distinguished values for the structural metadata. Make some types more strict by choosing the correct subclasses. Set DISCONT flag on buffers after a component switch. Take the last partition from the random index pack for the footer partition of the header partition doesn't reference the footer partition. This gives us the final structural metadata for some more files in the beginning.
