ENH: Auto-detect driver from filename extension when writing

[jorisvandenbossche]

We currently already have some limited, hardcoded version of this using:

pyogrio/pyogrio/raw.py

Lines 19 to 27 in 75e8f13

	DRIVERS = {
	".fgb": "FlatGeobuf",
	".geojson": "GeoJSON",
	".geojsonl": "GeoJSONSeq",
	".geojsons": "GeoJSONSeq",
	".gpkg": "GPKG",
	".json": "GeoJSON",
	".shp": "ESRI Shapefile",
	}

But now we have initial support for internally using the GDAL driver metadata (#103, first used in #189), we could generalize this based on the extension information stored in the driver metadata.
