How to use the tuyapi/lib/message-parser.js.MessageParser function in tuyapi

function discoverLocalDevices() {
    server = dgram.createSocket('udp4');
    server.on('listening', function () {
        //const address = server.address();
        adapter.log.info('Listen for local Tuya devices on port 6666');
    });
    const normalParser = new MessageParser({version: 3.1});
    server.on('message', function (message, remote) {
        adapter.log.debug('Discovered device: ' + remote.address + ':' + remote.port + ' - ' + message);
        let data;
        try {
            data = normalParser.parse(message)[0];
        } catch (err) {
            return;
        }
        if (!data.payload || !data.payload.gwId || data.commandByte !== CommandType.UDP) return;
        if (knownDevices[data.payload.gwId] && knownDevices[data.payload.gwId].device) return;
        initDevice(data.payload.gwId, data.payload.productKey, data.payload, ['name']);
    });
    server.on('error', err => {
        adapter.log.warn('Can not Listen for Encrypted UDP packages: ' + err);
    });
    server.bind(6666);

function checkDiscoveredEncryptedDevices(deviceId, callback) {
    const foundIps = Object.keys(discoveredEncryptedDevices);
