Add data relay on UDP in EmotiBit Oscilloscope

[nitin710]

Request

• Add UDP transmission option to Oscillosocpe

Describe the solution you'd like

• When UDP is enabled in the send data via list, data is relayed to a port using UDP

[nitin710]

Implementation proposal

• start a new UDP cxn
  • https://github.com/EmotiBit/ofxEmotiBit/blob/ac58a818818aff010751dfe605270462ea7420ec/src/EmotiBitWiFiHost.h#L52
• Send data to the UDP port, as data is processed in slowResponse

Think about

• Where should the port details be stored?
  • emotibitCommSettings?
• structure of UDP section in the json file

{
  "sendData": {
    "OSC":{
      "ip":"",
      "port": ""
    },
    "UDP":{
      "ip" : "",
      "port":"1122"
    }
}

• this changes the structure of oscOutputSettings.xml
