docs: Get all coordinates from a {@link FeatureCollection} object, returning a
  {@code List} of {@link Point} objects.
  
  @param featureCollection the {@link FeatureCollection} that you'd like
  to extract the Points from.
  @param excludeWrapCoord  whether or not to include the final coordinate of LinearRings that
  wraps the ring in its iteration. Used if a {@link Feature} in the
  {@link FeatureCollection} that's passed through this method, is a
  {@link Polygon} or {@link MultiPolygon} geometry.
  @return a {@code List} made up of {@link Point}s
