Currently, the JDBC sink connector does not support Oracle's SDO_GEOMETRY type columns.

I propose adding support for SDO_GEOMETRY using a similar approach as in GeometryType of PostgreSQL dialect.

Ingestion of WKB can be achieved using the Oracle function SDO_UTIL.FROM_WKBGEOMETRY(TO_BLOB( ? ), ? ).

I have working code that implements this functionality and would like to contribute it to the project.
