There is no way to pass some g-recaptcha tag attributes / grecaptcha.render parameters

There seem to be no way to pass some important params like e. g. expired-callback or error-callback.

@silverdr you're absolutely right that its light on config at the moment and does not support these. I'd welcome a PR, but in the meantime I'm going to add this to a backlog of things that need to be done.
