avformat/argo_brp: allow v1.1 ASF streams to have a non-22050 sample rate in certain circumstances
It seems that in files where the BASF block isn't first, v1.1 ASF streams are
allowed to be non-22050. Either this format is really inconsistent, or
FX Fighter and Croc just ignored the sample rate field, requiring the v1.1
restriction in the first place.
This bumps the version to 1.2 in these streams so they're not "corrected".
Found in Alien Odyssey games files in:
./GRAPHICS/COMMBUNK/{{COMADD1,COMM2_{1,2,3E},COMM3_{2,3,4,5,6}},FADE{1,2}}.BRP
