ESP32S2 support and Error Handling

PyDOS no longer crashes to REPL when a python script has an error.

ESP32S2 microcontroller has been tested against PyDOS and many of the external routines.

To run PyDOS on CircuitPython on an ESP32S2 board without memory and recursion limitation problems a custom CircuitPython UF2 file must be built with the MICROPY_ENABLE_PYSTACK parameter disabled and the MICROPY_STACKLESS parameter enabled.
