Request: A one query method to cover all of them

[halvardssm]

Hi! I really appreciate the work you have put into this library!

When automating queries it's not always possible to know if a request will be a query or an execution. Would it be possible to have one method exposed which handles any type of query? Currently, if I use execute, it will throw an error if the response is empty (e.g. from a select statement), and if I use query it will time out if I use an insert/delete/update statement. Maybe changing execute to not throw on empty but rather return undefined or null would be an option?

Thanks!

For ease of use, this is a point worth considering, I will add it to the future list
