Add fixes and tests for 0-, 1-, and 2-vertex geoloops and holes #816

Closed nrabinowitz closed 6 months ago

nrabinowitz commented 6 months ago

This includes the fixes from #800, plus one more fix for estimating a 1-vertex polygon. Includes the following tests:

0-vertex polygon, all modes
1-vertex polygon, all modes
2-vertex polygon, all modes
polygon with 0-vertex hole, all modes
polygon with 1-vertex hole, all modes
polygon with 2-vertex hole, all modes

Hopefully #800 will be green once rebased on top of this.
