// This class aligns responses with response headers from extra info:
// - Network.requestWillBeSent, Network.responseReceived, Network.loadingFinished/loadingFailed are
// dispatched using one channel.
// - Network.requestWillBeSentExtraInfo and Network.responseReceivedExtraInfo are dispatched on
// another channel. Those channels are not associated, so events come in random order.
//
// This class will associate responses with the new headers. These extra info headers will become
// available to client reliably upon requestfinished event only. It consumes CDP
// signals on one end and processResponse(network.Response) signals on the other hands. It then makes
// sure that responses have all the extra headers in place by the time request finishes.
//
// The shape of the instrumentation API is deliberately following the CDP, so that it
// is clear what is called when and what this means to the tracker without extra
// documentation.
