[Insight-developers] GDCM Failure

The DICOM images appear to have been created by misuse of my
dicom3tools, perhaps during anonymization.

Specifically:

- there is an invalid root UID of 0.0.0.0 - the tools should be
   recompiled with an appropriate root in the configuration

- the study and series UIDs are not the same for the set - this
   can be achieved by using the -stamp option to dccp or similar,
   or by manually replacing (-r) these two UIDs with the UIDs
   from the first instance created

- several attributes have been removed when they should have been
   replaced with zero length (PatientBirthDate, ReferringPhysicianName,
   AccessionNumber)
