We now need to explicitly set the proper image IO (GDCMImageIO), but
also we must tell
the ImageFileWriter to not use the MetaDataDictionary from the input
but from the GDCMImageIO
since this is the one that contains the DICOM specific information
The GDCMImageIO object will automatically detect the pixel type, in
this case unsigned
char and it will update the DICOM header information accordingly.

You can even manually change any tab you do not like, or that must be
updated, have a look at ImageReadDicomSeriesWrite.cxx

(for some reason I cannot find it in the ItkSoftwareGuide, must have
been added after the latest pdf generation).
