* \brief Pack/Unpack 12 bits pixel into 16bits
* \li You can only pack an even number of 16bits, which means a multiple of 4 (expressed in bytes)
* \li You can only unpack a multiple of 3 bytes
*
* This class has no purpose in general purpose DICOM implementation. However
* to be able to cope with some early ACR-NEMA file generated by a well-known
* private vendor, one would need to unpack 12bits Stored Pixel Value into a
* more standard 16bits Stored Pixel Value.
