  #### leave

  ```
  /leave|{"id":"..."}
  ```

  When a leave message is received from a peer, we check to see if that is
  a peer that we are managing state information for and if we are then the
  peer state is removed.

  ##### Events triggered in response to `/leave` messages

  The following event(s) are triggered when a `/leave` action is received
  from a peer signaller:

  - `peer:leave`

    The `peer:leave` event is emitted once a `/leave` message is captured
    from a peer.  Prior to the event being dispatched, the internal peers
    data in the signaller is removed but can be accessed in 2nd argument
    of the event handler.

      signaller.peers.delete(data.id);
