ENH: Shorten color table csv file column names

CodingSchemeDesignator -> CodingScheme
AnatomicRegion -> Region

Changing from AnatomicRegion to Region also allows more flexible use of the file format (from microscopy to astronomy).
The codes will tell if it is an anatomical region or something else. When exporting to DICOM and the region code defines an anatomical region, it will written there as "anatomical region", but the csv file format can be more generic.
