Add support for retrieving an event class by it's CDP method name

[zaygraveyard]

While trying to use trio-chrome-devtools-protocol, I encountered the need to dynamically retrieve an event class by it's CDP method name in order to wait_for() it or listen() to it

Is it possible to add support for that use case?

Maybe something like cdp.utils.get_event_class():

def get_event_class(method: str) -> typing.Any:
    return _event_parsers[method]
