Usage

    // subscribe to event
    rfidReader.RfidRead += RfidReaderOnTagRead;

    // subscribe to IObservable
    rfidReader.Subscribe(new RfidObserver());

    return Task.CompletedTask;
}

public override Task Run()
{ 
    rfidReader.StartReading();

    return Task.CompletedTask;
}

    }

    Resolver.Log.Error($"From event - Error {e.Status}");
}
