No data returned below RN 0.65

[Rays15]

Describe the bug
isBeingObserved is always false below RN 0.65, Because addListener will not execute.

public class RNSensor extends ReactContextBaseJavaModule implements SensorEventListener {
  ...

  private Boolean isBeingObserved = false;

  ...

  @Override
  public void onSensorChanged(SensorEvent sensorEvent) {
    if(!isBeingObserved) {
      return; // avoid all the computation if there are no observers
    }
    ...
  }

  ...

  // this is called by RN when the first listener is registered
  // not implementing this method will cause a warning on RN 0.65 onwards
  @ReactMethod
  public void addListener(String eventName) {
    isBeingObserved = true;
  }

  // this is called by RN when the last listener is deregistered
  // not implementing this method will cause a warning on RN 0.65 onwards
  @ReactMethod
  public void removeListeners(Integer count) {
    isBeingObserved = false;
    stopUpdates(); // maybe only calling `stopUpdates()` is enough
  }
}
