This patch makes dcm2niix more robust to manipulation of Philips DICOM enhanced images.
Critical diffusion parameters are stored Philips private SQs such as 0018,9117. Conversion to implicit VR using
dcmconv +ti ex.DCM im.DCMremoves the "SQ" VRs, and the resulting tag explicitly provides the length for the whole SQ. The private SQs effectively become old-DICOM style shadow groups. This requires an explicit dictionary that identifies which private tags are actually SQs.The result code handles issue 189 while attempting to maintain as much robustness as possible.
