Is EWKB SRID preserved?
If EWKB contains SRID, the converter detects it and includes it as a CSV property column.
What geometry types are supported?
Standard WKB/EWKB geometry types supported by wkx: Point, LineString, Polygon, Multi geometries, and GeometryCollection.
What does centroid-only mode do?
It exports a smaller table focused on centroid and area columns, without WKT/bbox/topology columns.
