Serialization: Changed write order for extrude, tessellate, altitudeModeGroup

[ghost]

Changed write order on serialization for extrude, tessellate for write_point() and extrude, tessellate, altitudeMode for write_geom_props so that the result validates against http://schemas.opengis.net/kml/2.2.0/ogckml22.xsd

This is just an issue of the tests now being out of date with the representation. You can update test_write_point and test_write_polygon to put the correct attributes first so that this passes. Also feel free to add the change for #23 here

Ok, I changed the order for custom elements/children in write_placemark and tried updating the Point+Polygon tests as well.

However, the tests still fail since write_polygon now also needs write order changed. What I've changed the string representation to for test_write_point and test_write_polygon validates against http://schemas.opengis.net/kml/2.2.0/ogckml22.xsd so far.

I can look into write_polygon this as well if you'd like, but should that be in another PR or this one?

Feel free to put the changes to write_polygon in here as well. It also looks like there are some formatting issues in CI

I've changed write order in write_polygon and the formatting issue in test_write_point. Seems to pass tests now.

Thanks for making those updates! I think this should be good, but I'll try to take a closer look later today
