Description

This issue is about coming up with a new (or updated) SpatialStrategy abstraction. The primary goal is to remove a dependency on Spatial4j. Some SpatialStrategies will not use/require the abstractions in Spatial4j. Strategies that support more complex/interesting cases may require Spatial4j still.

Research direction

Start by locating the existing SpatialStrategy abstraction and identifying where it depends on Spatial4j. Review the spatial strategy implementations to determine which can operate without that dependency; done means a revised abstraction supports those strategies while preserving Spatial4j for more complex cases.
