Observe cancellation by client

See original GitHub issue

node-coap currently does not support proactive cancellation via GET with Observe=1.

In server.js, the _handle() function should probably try to find the corresponding ObserveStream via the token when request.headers['Observe'] === 1 instead of producing a new response with response = new Message(packet, function(response, packet). The ObserveStream needs to be closed. Sending the last (cached) response/notification with that token should work; otherwise, ObserveStream could also take a callback to produce a final response.
