@balazsracz This is a rather large PR but contains the support code for arduino-esp32 2.0. The ESP32-S2 TWAI driver is broken in arduino-esp32 2.0.0 due to https://github.com/espressif/esp-idf/issues/5604 which has been...

@balazsracz Can you take a look at the STM32 build failure? I'm not certain what the issue is entirely: ``` 2022-08-04T14:19:38.2185491Z In file included from /home/runner/Arduino/libraries/OpenMRNLite/src/openlcb/ConfigRenderer.hxx:42, 2022-08-04T14:19:38.2185715Z from /home/runner/Arduino/libraries/OpenMRNLite/src/openlcb/ConfigEntry.hxx:45, 2022-08-04T14:19:38.2185975Z...

@balazsracz I think the work in this can be simplified some by dropping the IDF v3.x (arduino-esp32 1.0.x) support. Do you think it would be worthwhile to do that now...

I've used the MultiConfigurePC object successfully on the ESP32-S2 (though it should work on others), I encountered the same limitation and modified the [Esp32Gpio](https://github.com/bakerstu/openmrn/blob/md-esp20/src/freertos_drivers/esp32/Esp32Gpio.hxx) code to not use `GpioWrapper`.
