Changes:
The existing samples are truncated, so these are kind of stuck with old school magic byte pattern matching.
Therefor I replaced them with original files.
The updated Sony file type
.arwhas been a bit of guess. It basically looks for a tag, which looks like a Sony private tag. Other.arwmay or may not have this tags.Warning: fixtures are very large, 25 MB each!!!Truncated samples to 100.000 bytes each. This is enough to read it's tags.
Fixes #480
