Use events

in this MR I am replacing the on-response, on-error and on-progress arguments for the custom web components by the usage of events, see https://github.com/bitovi/react-to-web-component/blob/main/docs/api.md#event-dispatching

additionally I am revising how the default response, error and progress handlers are skipped.
