Feat [transform-translate] handles geometry preservation

[hadbn]

Adds the option aroundCenter to the function transformTranslate. When used, transformTranslate, will translate the centroid of the geometry. The points of the geometry will be reconstructed using (in pseudo-code):

centroidOriginal = centroid(geometry)
translatedCentroid = translate(centroid) //here using rhumbdestination and the translation parameters
for each point of geometry {
    distanceToCentroid = distance(centroidOriginal , point)
    bearingFromCentroid = bearing(centroidOriginal , point)
    translatedPoint = destination(translatedCentroid, distanceToCentroid, bearingFromCentroid)
}

This allows for instance to have a circle as a result of the translation of a circle, instead of the highly deformed shape we can observe.
The difference between using the option or not is only mainly visible for "big geometry" (when the earth curvature plays a role).

In this example the black circle is translated. aroundCenter is set to true for the blue geometry, and to false for the red one.

All tests are updated to take this evolution into account.
