Idea: Support LINESTRING Z/ZM/M wkt syntax

The from_wktgeometry() and sdo_geometry() functions don't support the LINESTRING Z/ZM/M syntax or the (MULTI)LINESTRING Z/ZM/M syntax.

@_jum : The extended OGC syntax with z-coordinates/measures seems to be not supported in ORACLE as M, Z, ZM:

 LINESTRING (10.05 10.28 , 20.95 20.89 )

 LINESTRING (10.05 10.28 , 20.95 20.89 )

 LINESTRING ZM (10.05 10.28 , 20.95 20.89 )

Could the from_wktgeometry() and sdo_geometry() functions be enhanced so that they support (MULTI)LINESTRING Z/ZM/M syntax?
