[BUG] Hemisphere map not correctly set for mpin_zfish_1um_v1.0

[PolarBean]

Describe the bug
My understanding is that the hemisphere map should be a binary image in the same shape as the template with a 0 or 1 labeling each hemisphere as either left or right hemisphere respectively. However the provided hemispheres.tiff file appears only to have labeled the left hemisphere for voxels where y==0 (ie, only one row). Everything else is labeled as 1.

To Reproduce
open both hemispheres.tiff and reference.tiff in itksnap. set the hemispheres colourmap to Jet and it will become apparant.

Expected behaviour
All voxels in the left hemisphere should be labeled 0.

Thanks @PolarBean, this does seem to be a long undiscovered error.

@alessandrofelder, @viktorpm does the validation script check the hemisphere files?

Not yet, but that's a good idea!
