@brief Enable wakeup from sleep mode using specific GPIO @param gpio_num GPIO number @param intr_type Wakeup on high level (GPIO_INTR_HIGH_LEVEL) or low level (GPIO_INTR_LOW_LEVEL) @return - ESP_OK on success - ESP_ERR_INVALID_ARG if gpio_num is not an RTC IO, or intr_type is not one of GPIO_INTR_HIGH_LEVEL, GPIO_INTR_LOW_LEVEL.
