IMHO ignoring version in read_header might be OK in this case.

Another way would be erroring out and say use ignore_version option. Don't 
think it's necessary here, but would maybe be a bit more honest and we could 
ask for samples at the same time.

Probably more problematic is the part completely removing the check for known 
version from the probe function. Shouldn't that stay?
