wireproto: introduce type for raw byte responses (API)

Right now we simply return a str/bytes instance for simple
responses. I want all wire protocol response types to be strongly
typed. So let's invent and use a type for raw bytes responses.

.. api::

   Wire protocol command handlers now return a
   wireprototypes.bytesresponse instead of a raw bytes instance.
   Protocol handlers will continue handling bytes instances. However,
   any extensions wrapping wire protocol commands will need to handle
   the new type.
