sqlite_plus_geo examples

dart run bin/main.dart opens an in-memory sqlite_plus database and runs four demos:

1. Facilities within 5 km of a point, ordered by spherical distance.
2. A GeoJSON feature collection imported and queried offline.
3. The administrative polygon that contains a coordinate.
4. ST_Intersection of two parcel squares.

The program prints:

Clinic | North | 2 | 2.0 | true

A map widget is not a dependency. Convert a stored point with point.toMapPosition(). Pass longitude and latitude to the widget's own point type. X is already longitude.
