Research direction

Start by reproducing the MyBatis-Plus mapper batch insert with the JDBC TAOS-WS connection, using the documented super-table approaches and the foreach values case described in the issue. Compare the failures with the same inserts over JDBC TAOS-RS; done means multi-row insertion works through TAOS-WS without the single-table or column-count errors.
