[MetaCRS] Specifying Coordinate Order in Test Data File...Again

Makes sense.  So in this case, since the projection is ESPG:2227, the
ordinate order should be XY.

Am I right in thinking that some CS specification formats don't encode
the ordinate explicitly (eg ESRI, PROJ4) ?   Not sure if that's an
issue for the test files or not - I suppose it's really an issue for
the library itself to try and figure out this information somehow (eg
by assumption or exception)
