/* BistableRelay
 * This class can be used to controll bistable relay.
 * Supla device will send short impulses (<0.5 s) on GPIO to toggle bistable
 * relay state.
 * Device does not have knowledge about the status of bistable relay, so it
 * has to be read on a different GPIO (statusPin)
 * This class can work without statusPin information, but Supla will lose
 * information about status of bistable relay.
