Print statements in flutter_gpiod package

[JesseRiemens]

The flutter_gpiod package contains some print statements that aren't useful:

 print('before isolate.spawn');

    Isolate.spawn(
      _eventIsolateEntry2,
      [
        receivePort.sendPort,
        epollFd,
      ],
      onError: errorReceivePort.sendPort,
      debugName: 'flutter_gpiod event listener',
    );

    print('after isolate.spawn');

Can these be removed?
