Description
-------

This task is about implementing full support for the KML extrude tag. It can occur as a child element of <Point>, <Polygon>, <LineString> and <LinearRing>. See https://developers.google.com/kml/documentation/kmlreference for details.
- Fix KmlextrudeTagHandler::parse, which does a faulty boolean check if( parentItem.nodeAs<GeoDataGeometry>() ). Change both checks in that area to use
parentItem.is<GeoData...>() for all fours elements (GeoDataPoint, GeoDataLineString, GeoDataLinearRing, GeoDataPolygon). Assign them the extrude value as necessary.
- Extend all Kml*TagWriter.cpp files for Point, LineString, LinearRing and Polygon to write the extrude tag if extrude is active (so either <extrude>1</extrude> ends up in the KML file or nothing).
- Extend the .kml files in tests/data/ to have at least one instance with <extrude>1</extrude> for all four tags


I fixed the reading procedure of extrude tag and extended the tests data for extrude tag. I think that the solution satisfies the task.
