Missing definition of clearDeviceDiscoveredListener() and unsubscribe() functions

[julianCast]

The method clearDeviceDiscoveredListener() doesn't seems to be typed in d.ts file, neither unsubscribe(). https://github.com/don/BluetoothSerial#cleardevicediscoveredlistener

@julianCast the type script definitions are part of Ionic Native. Can you submit a pull request to that repo with the missing definitions? https://github.com/ionic-team/ionic-native/blob/master/src/%40ionic-native/plugins/bluetooth-serial/index.ts
