A way to stop dscKeybusInterface
Hi there,
Is there is a way to stop dscKeybusInterface?
I mean, like dsc.begin but dsc.stop

I am integrating the code with a different Wifi manager (IoTWebconf instead of WiFiManager) and for some reason (that I don´t know) if dscKeybusInterface is started, it fails to connect to WiFi. 
So I workarounded starting dscKeybusInterface after Wifi connection is stablished.

```
if (iotWebConf.getState() == IOTWEBCONF_STATE_ONLINE) {
                if (!DSCBegined){
                    // Starts the Keybus interface and optionally specifies how to print data.
                    // begin() sets Serial by default and can accept a different stream: begin(Serial1), etc.
                    dsc.begin();
                    DSCBegined = true;
                    Serial.println(F("DSC Keybus Interface is online."));
                }
        doDSC();
      }
```

And then it´s work fine, but if Wifi connection is lost, it will retry connecting with no success because dscKeybusInterface is begined. So I need stop dscKeybusInterface until Wifi connection is restablished and then dsc.begin again.

Can anyone suggest a way to do this?

Thanks in advance for your sugestions.
Best regards.
