Nullability of Polygon coordinates

Not a bug, but there seems to be some inconsistency with the nullability of coordinates.

CoordinateContainer.coordinates is not annotated to indicate what the nullability is. Must of the static analysis treat this as unknown, and you may or may not check.

All the subclasses annotate the method as NonNull, except for Polygon, which marks it as Nullable. Seems strange that single implementation can be null but all the others cannot. And if I access from the parent interface, and don't get any warnings about not checking for null.

According to GeoJson spec coordinates on all Geometries except GeometryCollection should be @NotNull

Upon further inspection MultiPoint and Polygon both need to be updated
