config reset

[SpComb]

Needs support for some kind of hardware config reset button, or a config error -> bootloop is unrecoverable.

This should inhibit loading of /config/boot.ini, and boot with defaults.

Should probably not enter a bootloop with #3 type configuration errors.

Requires some kind of wifi bootstrap... like defaulting to AP mode.

Erase config partition using esptool.py

ESPPORT=/dev/ttyUSB0 docker-compose run --rm flash /opt/ESP8266_RTOS_SDK/components/esptool_py/esptool/esptool.py --chip esp8266 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset erase_region 0x200000 0x100000

a149f9a implemented support for reading the NodeMCU FLASH button on GPIO0. It needs to be held for >5s, and the configuration will be reset and the system restarted.
