This function handles the case where the actual bits per pixel per band is less then the actual bpppb AND where the data is std::left justified.
This shifts the data so that it is right justified. As of now, this function is untests as I don't have any std::left justified data (the NITF spec discourages using it – probably because it is such a PITA)
