The file was previously a direct copy of the EPSG derived datum.csv
distributed with libgeotiff.  However, I have added a new column,
ESRI_DATUM_NAME, that isn't part of the EPSG table, nor is part of the
libgeotiff version of datum.csv.  So to avoid confusion I have renamed
the file.

As you might guess, the column is used as part of the OGRSpatialReference
services for converting between ESRI WKT .prj files and a more EPSG based
set of datum names.
