CRS.toMapCoord does not actually use grivation

[perliedman]

Looking at the code, the coordinate is rotated but the value isn't used in the return value.

A correct implementation should look something like this but with TdPoly support:

function toGrivationPaperCoord(crs, coord) {
  const map = [
    (coord[0] - crs.easting) / hundredsMmToMeter / crs.scale,
    (coord[1] - crs.northing) / hundredsMmToMeter / crs.scale,
  ];
  coord = rotate(map, crs.grivation);
  return coord;
}
