* This function uses external wakeup feature of RTC controller.
* It will work even if RTC peripherals are shut down during deep sleep.
*
* @note Currently this doesn't actually work if RTC_PERIPH domain is
* powered down. This is a known issue which will be resolved soon.
* For now, unless esp_deep_sleep_pd_config function is used to
* power down RTC_PERIPH domain, it will be kept on during deep sleep,
* slightly increasing power consumption.
*
* This feature can monitor any number of pins which are in RTC IOs.
* Once any of the selected pins goes into the state given by level argument,
* the chip will be woken up.
