level 2
will also print the seek head entries, the cue entries and the file position
at which each Matroska element can be found at.

level 3
will print some information that is not directly connected to a Matroska
element. All other elements only print stuff about the elements that were
just found. Level 3 adds meta information to ease debugging (read: it's
intended for developpers only). All lines written by level 3 are enclosed
in square brackets to make filtering them out easy.
