TODO

• [ ] Prepared geometry, spatial indices (LibGEOS) (probably can't be done as GDAL OGR is not directly compatible)
• [x] IGeometry should be IGeometry{WKBType} for easy Schema detection, fix upstream
• [ ] Empty geom column name fix should be moved upstream
• [ ] More drivers selected on extension
• [x] CRS stored in metadata
• [x] Work on Geointerface integration
• [ ] Work on spatial joins/filters
• [x] Override showing of WKT geometry on print for performance
