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.
