any<T> method
Adds an endpoint for every method no other handler claims.
The counterpart to axum's any and shelf_router's all. A method with
its own handler still wins, so get(read).any(rest) sends GET to
read and everything else to rest.
Implementation
MethodRouter any<T>(Endpoint<T> endpoint, {int status = 200}) =>
on(Route.anyMethod, endpoint, status: status);
