title: Convert Multipolygon to Polygon in Python
body: <p>Is it possible to convert a <code>Multipolygon</code> into a <code>Polygon</code> which fills all holes or missing inner areas using <a href="https://shapely.readthedocs.io/en/latest/" rel="noreferrer">Shapely</a>? I have been trying since a while but I can't find it in the documentation. The following image I show an example of a multipolygon with those holes I want to fill, and those squares I want to remove.</p>
