2.10.0

• Speedup get_shortest_path method calls for GeoGraphs
• Implement custom KDTree for substantially faster closest node calculations
  • Note: Initializing a GeoGraph now requires building the KDTree which slows down imports (esp from scgraph_data)
  • This is worth the overhead, but a future release may find a way to delay this until needed.
• Update defaults for faster compute times
