        If geometry is a Polygon, it converts it into a MultiPolygon. If it's a GeometryCollection, it filters to create
        a MultiPolygon from any Polygons in the collection. Returns an empty MultiPolygon if no Polygon or MultiPolygon
        components are found.

        Args:
            geometry: A shapely geometry object (Polygon, MultiPolygon, GeometryCollection, etc.)

        Returns: MultiPolygon
