Subject: [PATCH] COMP: Add itkImageRegionConstIteratorWithIndex.h include for
 ITK6 compat

ITK upstream main (v6 prep) has trimmed transitive includes. BVeR.cxx uses
`itk::ImageRegionConstIteratorWithIndex` but did not include its declaring
header directly; under ITK 5.x the header was transitively pulled in via
one of the other ITK includes, but ITK upstream main now produces:

  BVeR.cxx:185:14: error: 'ImageRegionConstIteratorWithIndex' is not a member of 'itk'

Add the explicit include. Backward compatible with ITK 5.x (the header has
always existed under that name).
