Feature Request

Is your feature request related to a problem? Please describe:

• filter some DML events which can't be parsed in go-mysql, like the old MariaDB TIME/TIMESTAMP/DATETIME binary format.
• filter some DMLs events which can be very large (and heavy to parse), like generated with insert into t2 select * from t1 (which will hold the whole table in one Write_rows event).

Describe the feature you'd like:

filter DML Write/Update/Delete rows event based on the TableMapEvent of the txn in https://github.com/siddontang/go-mysql, then there is no need to parse the body of these events.

Describe alternatives you've considered:
