Expose an interface to sqlite3_file_control

Feature or enhancement

Proposal:

sqlite3_file_control can affect the semantics of a sqlite3 database, but is not exposed by the sqlite.Connection class. In particular, I would like to use the SQLITE_FCNTL_PERSIST_WAL opcode, which ensures that callers can open a WAL-mode database on a read-only mount even when the writers have closed the DB.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
