The PolygonHull class computes concave hulls, but respects the boundary of the polygon in doing so: the new hull does not cross into the area of the input polygon.

Feature is equal to [ST_SimplifyPolygonHull](https://postgis.net/docs/ST_SimplifyPolygonHull.html) in PostGIS.

> Computes a simplified topology-preserving outer or inner hull of a polygonal geometry.
> An outer hull completely covers the input geometry.
> An inner hull is completely covered by the input geometry.
> The result is a polygonal geometry formed by a subset of the input vertices.
> MultiPolygons and holes are handled and produce a result with the same structure as the input.
> https://postgis.net/docs/ST_SimplifyPolygonHull.html

Utilizes `GEOSPolygonHullSimplify` method introducesd in [GEOS 3.11.0](https://github.com/libgeos/geos/releases/tag/3.11.0).
