This function sends the device to sleep. For ZUNO_SLEEPING_MODE_SLEEPING mode Z-Uno will wake up after wakeup period (set up via Wakeup Command Class) or on INT1 going LOW or Key Scanner detects press. For ZUNO_SLEEPING_MODE_FREQUENTLY_AWAKE mode Z-Uno will wake up on packet recieved, after a wake up period defined using zunoSetBeamCountWU() or on INT1 going LOW or Key Scanner detects press.
