Bug: DICOM file has incorrect signedness

Reported by:	omero-qa	Owned by:	mlinkert
Priority:	minor	Milestone:	5.0.6
Component:	Bio-Formats	Version:	5.0.4
Keywords:	n.a.	Cc:	jwarren@…

Description

https://www.openmicroscopy.org/qa2/qa2/qa/feedback/9532/

See also http://www.openmicroscopy.org/community/viewtopic.php?f=5&t=7635. The pixel type is set to uint16, but should be int16 (to have a black background with an X-ray artifact).

We're currently only using the PixelRepresentation? tag to determine sign; probably we will need to check PixelIntensityRelationshipSign? (0028, 1041) instead or in addition.
