/**
* \brief Class to read/write a DataElement as ExplicitImplicit Data Element
* \details This class gather two known bugs:
* 1. GDCM 1.2.0 would rewrite VR=UN Value Length on 2 bytes instead of 4 bytes
* 2. GDCM 1.2.0 would also rewrite DataElement as Implicit when the VR would not be known
* this would only happen in some very rare cases.
* gdcm 2.X design could handle bug #1 or #2 exclusively, this class can now handle
* file which have both issues.
* See: gdcmData/TheralysGDCM120Bug.dcm
