  Fix issue 2245.  aifc now skips any chunk type it doesn't actually
  process instead of throwing errors for anything not in an explicit
  skip list.  This is per this spec: http://www.cnpbagwell.com/aiff-c.txt.
  Spec reference and test sound file provided by Santiago Peresón, fix
  based on patch by Hiroaki Kawai.
