I hacked ESP32RET so it also works with ESP32-S3 which doesn't have classic serial over bluetooth

I also added a simplified OBD2 layer to run on top of the esp32_can library that supports the newer ESP32-S3 (that sandeeps library doesn't (at least yet)). It's a fork and rewrite of sandeep's OBD2 code

I also made a VERY simple OBD2 car emulator which runs on ESP32-S3 and the like (with the esp32_can library)

Finally mostly just a fun "first": example code that is tested and runs on the new ESP32-C6 that has TWO built in CAN controllers :-)
