[proposal] Method to wait for re-connect after connection loss

[masseelch]

Currently I do it this way, but find it rather unclean:

for {
  if !ws.IsConnected() {
    time.Sleep(time.Second * 2)
    continue
  }

  // Do stuff with connection
}

One idea I have is to export the getBackoff() method to wait for the correct time until trying to read a new message. Another idea is to have a method WaitConnection() / EnsureConnection(), which blocks until the connection is reestablished. I am happy to create a PR for either of the proposals.
