 * Finds the difference between multiple {@link Polygon|polygons} by clipping the subsequent polygon from the first.

 * @function

 * @returns {Feature<Polygon|MultiPolygon>|null} a Polygon or MultiPolygon feature showing the area of `polygon1` excluding the area of `polygon2` (if empty returns `null`)
