• ESP32 API 3.x

Moving from API 2.0.17 to 3.x.
Espressive massively broke the compatibility from 2.x to 3.x which is the main reason to stick with 2.0.17

Changes are saved in a separate branch: https://gitlab.com/rocrail/wio/-/tree/ESP32_API3?ref_type=heads

• https://github.com/miwagner/ESP32-Arduino-CAN

Replace the missing include file in CAN.c line 37

#include "esp_intr.h"

with

#include "rom/gpio.h"
