Geopandas: Implement concave_hull

[chay0112]

Use case:

• Add support for Geoseries.concave_hull

Description:

• Implements GeoSeries.concave_hull, which computes the concave hull for each geometry in the series. The concave hull is the smallest concave polygon that contains all points of the geometry, controlled by a ratio parameter that determines the level of concavity and an option to allow holes. For geometries with fewer than three points, the result is a LineString or Point. This method ensures each geometry in the series is replaced by its concave hull representation, matching the behavior of GeoPandas.
