Cascade constructor
A class that supports calling multiple handlers in sequence and returns the first acceptable response.
By default, a response is considered acceptable if it has a status other than 404 or 405; other statuses indicate that the handler understood the request.
If all handlers return unacceptable responses, the final response will be returned.
final handler = Cascade()
.add(staticAssetHandler)
.add(router)
.handler;

: null,
