ESP32 Firmware Image support
New build interface can handle several formats, but the ESP image format is missing:
- https://docs.espressif.com/projects/esptool/en/latest/esp32/advanced-topics/firmware-image-format.html
- https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/app_image_format.html
After #415, the esp image format has been implemented, though only esp32-c3 is curently supported. Adding support for the others esp32xx afaik is very easy and we should set only a couple of constants. Should we close this?
