More regression tests #60
Description
DPXTests.java references only 1 DPX , MXFTests.java checks a bit more MXF files, this is definitely not enough for doing a QA, there are many flavors (bit depths, color spaces, packing style...) of DPX, many scanners which don't follow exactly then specs (Scanity, Lasergraphics and Diamant have a custom way to pad the end of lines which are not 32-bit boundaries), many scanners with extra fields.
Modifications are not tested.
