refactor(callbacks): remove the cb argument

BREAKING CHANGE: Registered callbacks now return values rather than sending them as a callback.

Previously the cb needed to be called to return to the client, now it will happen once the function closes. i.e.

cb(string, string, false) -> return string, string, false
