+++ This bug was initially created as a clone of T5593 +++

A unit test should test some aspects of reading DICOM series. This is a sketch for such a test:

• Read a single slice with a negative value in tag (0018,0088) Spacing between slices
  • should be silently inverted because single slice spacing is not dramatic
  • see T5593

• Read a CT with a tilted geometry
  • some kind of clear error or hint should be produced
  • code checking this condition is available
  • see T1823

• Read a "normal" volume and check basic known properties such as
  • spacing
  • dimension
  • origin

Such a test or set of tests will help if ITK changes it's DICOM reading code.
