Pull request overview
Adds pickle support for core geometry objects by implementing __reduce__-based serialization (primarily via WKB), plus a couple of Shapely-compatibility additions (LineString boundary + Ring __geo_interface__) and accompanying tests.
Changes:
- Implemented
__reduce__forGeometry,Point,Ring,Line, andPoly(with helpers to preserve class on restore). - Added
Line.boundary(endpoints asMultiPoint, empty for closed lines) andRing.__geo_interface__. - Added pytest coverage for pickle roundtrips (including spawn-based multiprocessing) and boundary/geo-interface behavior; bumped project version.
