Comments
This function will set the data for the "Red", "Green" or "Blue" "Palette Color Lookup Table".
Before calling this function you must call LDicomDS::SetPaletteColorLUTAttributes to set the attributes of the "Palette Color Lookup Table", otherwise this function will fail and return DICOM_ERROR_LUT_DESCRIPTOR_MISSING.
