-----------------------------------------------------------------

I'd like to be able to implicitly transform a string into a geometry so that 
one can write the following query:

{{SELECT ST_AsText('POINT(-71.064544 42.28787)');}}

Instead of:

{{SELECT ST_AsText(ST_GeomFromText('POINT(-71.064544 42.28787)'));}}

Both Postgis and H2Gis supports this kind of conversion. Should I introduce a 
new SqlTypeTranform (TO_GEOMETRY)? Thanks a lot for your help, I'm still 
discovering the internals of calcite.

> Add functions to support WKB (well-known binary) and GeoJSON. This is made 
> possible by the switch to JTS in CALCITE-4294. The functions are:
>  * ST_AsEWKT
>  * ST_AsGeoJSON
>  * ST_AsWKB
>  * ST_GeomFromGeoJSON
>  * ST_GeomFromWKB
