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
--------------------------------------------
 01010000002DB29DEFA7C651C0B81E85EB51284540

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)))
-----------------------------------------------------------
