v0.1.1

Migrate to geoarrow-rs and arrow 58

• Arrow 57 → 58 with geoarrow-array, geoarrow-schema, geoarrow-expr-geo, and geo-traits dependencies
• GeoArrow-standard extension names: daft_geo.point2d/daft_geo.point3d → geoarrow.point
• Restructured internals: GeoArrowFfi trait + GeoPointArray wrapper struct replacing free functions, ready to extend to LineString, Polygon, etc.
• Accessors use GeoArrowArrayAccessor + PointTrait/CoordTrait from geo-traits instead of manual index math
• Removed benchmarks
