Does this library support returning responses from a Response instance?

Handler signature assume the only RequestEvent as arg. Response object could be returned as well as plenty other types.

We already have a Request-Response adapter. Does that suffice?

nhttp RequestEvent has a source request object, but with consumed body. Also it has newRequest - the clone of the original one with not consumed body (this one match for basic Req => Res). But it is a clone - not good for perf and memory, obviously. So thats why I made this PR.
