Add support for "Safe Private Attributes" (PS3.15), e.g. to dcmodify
PS3.15 lists "Safe Private Attributes" from various vendors, i.e. private data elements "which contain no identifying information and need to be
preserved during de-identification". Adding support for this list to e.g. dcmodify (with a new option in addition to --erase-private) could be useful.
CP-1672 adds more safe private attributes to PS3.15: ftp://medical.nema.org/medical/dicom/final/cp1672_ft_moresafeprivate.pdf
