sdkconfig: set CONFIG_ESP32_DEEP_SLEEP_WAKEUP_DELAY=2000 by default
...
To increase the chances that the examples work out of the box, this
change is raising the default deep sleep wakeup delay to 1ms.
If GPIO15 is low at startup, ROM code takes less time to execute
(because no logging is performed), so more time may be needed to allow
flash chip to become ready.
