   * simplifying OpenDML AVI handling.
   * adding code to skip over JUNK. It turns out that video editing
     software uses junk to resize ix## chunks without actually
     scrubbing the data. That trips up our packet extraction
     code since it recognizes ix## entries as "packets". Basically
     we have to skip over JUNK chunks for exactly the same reason
     we have to skip over ix## entries.

further opt is easily possible but could lead to overflows depening upon coefficient range, so this wont be done yet as it would make the code somewhat less flexible
