add of Xiaomi Mijia BT4.0 clock temperature and humidity sensor (LYWSD02)

Browse Source 
and enable multiple services data readings for Mijia standard device. Indeed the new version seems to publish several service data compared to old ones.
Please note that I'have update the library with the work of @fguiet
