Feature Request: Support for sqlite3_update_hook

[cuberoot]

I am currently working on a project where it would be very helpful to receive event callbacks on updates. This could be implemented using this: https://www.sqlite.org/c3ref/update_hook.html

There's a half finished PR on node-sqlite3 here, but I would rather use better-sqlite3.

Hey, this has been requested before in #62

Turns out user-defined functions + triggers are much more powerful and easy to use in better-sqlite3.

Yup, this is a duplicate of #62.
