ENH: Enable SecondaryCaptureImagePlaneModel in GDCM

This enables support for reading image orientation patient and image
position patient from DICOM secondary capture images.

This addresses needs such as reading Visible Human DICOM color images in
3D Slicer:

  NA-MIC/ProjectWeek#875

and reading highdicom derived secondary capture DICOM in ITK-Snap:

  ImagingDataCommons/highdicom#247

Update the RGB tests' baseline that were using a .png baseline because they now
output spatial metadata.
