Re: [I] GeoArrow Support? [arrow-adbc]

   GeoArrow defines both "serialized" and "native" array representations. The idea being that even if the geometries are encoded as WKT/WKB, we still want to be able to associate the string/binary column with a spatial Coordinate Reference System. 
   
   So the simplest way to have GeoArrow support is to slap on the `geoarrow.wkt` or `geoarrow.wkb` extension metadata onto the output from any system supporting those types.
