add support for alternative stripe payment methods (push)
so far we support credit cards, but would be nice to also offer other methods via bank transfer (giropay/sofortüberweisung and others)
Some of these methods are async, some require redirecting the user to their bank's site for authentication and back. And most/all of them are specific to some regions or only some specific countries.
See URL for supported payment methods and a matrix showing whether it is async or whether it requires redirect
