Currently, SDO_GEOMETRY columns are omitted from the connector's events as it is an unsupported column data type.
We should investigate what's needed to support this.

Observations from https://github.com/debezium/debezium/pull/2854

• SDO_GEOMETRY values are not present in UPDATE statements that do not modify the column values. Need to investigate what happens if the UPDATE statement references an SDO_GEOMETRY column.
• SDO_GEOMETRY columns are present in DELETE statements but the value is provided as Unsupported Type despite the database having compatibility mode of 12.1 or later.
