Add the "EWKT" Geometry Encoding definition to GeometryReplacer and GeometryExtractor.
EWKT is a simple extension to WKT that allows to include the coordinate system with the geometry, for instance: "SRID=4326;POINT(-44.3 60.1)" instead of "POINT(-44.3 60.1)"

EWKT is supported by Postgis and can be found in many open datasets.
