WKT might contain a SRID

[jze]

I found a CSV file that contains a column with Well-known-text (WKT) that includes a Spatial Reference System Identifier (SRID), e.g.
SRID=25832;POINT (574009.086492192 6028393.69530573)

Hi Jesper,

From what I understand:

• WKT is supported as a string format in frictionless-py (only documentation I found) but is not specified in TableSchema.
• SRID prefix support is not part of the standard WKT but a PostGIS extended version EWKT.
• it seems that the SRID is the major (if not only) difference between WKT and EWKT (from the previous link : )

a PostGIS specific format that includes the spatial reference system (SRID) identifier

Under these conditions, I think it is OK to add support for EWKT (even if the format name is kept as wkt), provided we leave some hint about it in the documentation.
