Bug 60898 - XSSFColor's getARGB() method returns a wrong color value when a workbook has a custom indexed color Missed this test. As part of the work I noticed the Enum was missing some values defined in the OOXML spec, so I added them. I've updated the test to reflect that those values are no longer invalid.
