useAnswer

function useAnswer<M, R, K>(
   channel,
   type,
   responder,
   options?): void;

Answer asks of one type for as long as this component is mounted.

A hook rather than a bare channel.answer call because a responder is a subscription: registering one in a render would leave the last unmounted component answering for the page.

One responder per type per channel — registering a second replaces the first, which is the same first-wins-then-replace rule answer has in core.
