feat: geodatafusion integration

[sunng87]

Fixes #176

This patch is only for demo. By combining geodatafusion, we will have PostGIS experience or even compatibility in next future releases.

And I wish geodatafusion could provide an entrypoint API to install all UDFs to SessionContext.

We can already include geodatafusion functions in datafusion-postgres. The next step is to check whether we can make the output format consistent with original postgis.

Original postgis, it's WKB in hex encoding without postgres' bytea hex encoding prefix (\x)

postgres=#  select ST_MakePoint(-71.104, 42.315);
                st_makepoint
--------------------------------------------

Current geodatafusion+datafusion-postgres:

postgres=> select st_makepoint(37.23, 123.22);
 st_makepoint(Float64(37.23),Float64(123.22))
----------------------------------------------
 (37.23,123.22)

postgres=> select st_asbinary(st_makepoint(37.23, 123.22));
 st_asbinary(st_makepoint(Float64(37.23),Float64(123.22)))
-----------------------------------------------------------

We can now get ewkb serialization:

postgres=# select ST_MakePoint(-71.104, 42.315);
 st_makepoint(Float64(-71.104),Float64(42.315))
------------------------------------------------
