Error logging callback

[borisgontar]

Please implement adding error logging callback as described in https://sqlite.org/errlog.html.

Any errors that occur will be propagated back to you as JavaScript exceptions. If you want to log an error, use a try-catch statement.

Actually I just wanted to catch SQLITE_NOTICE because rollback may take a long time and I need to ask users to wait.

+1 on this one, because of desire for a simple, one-line, foolproof catch-all for logging.

Thanks for creating/maintaining this package!

Another practical reason to support this is because this can be used to identify cases where SQLite is creating and using temporary automatic indexes

happy to submit a PR if I could get high level pointers to guide me!
