Board Generalizations and PyDOS improvments

• The PyDOS.py file is now all that's needed to load a generic instance of PyDOS
• The PyDOS setup.bat file has been streamlined
• A bug parsing blank lines in batch files was resolved
• The logic to identify GPIO functions for different microcontrollers has been put in the pydos_hw.py file so it doesn't have to be duplicated across multiple utility programs
• PyDOS now calculates the maximum wildcard length as determined by the Circuitpython or Micropython maximum recursion depth. Building custom *python images can increase this limit
• Many of the external demonstration programs now run across all the supported Microcontroller boards
• A new external program (pydospins.py) displays the GPIO pins being used for audio out and I2C.
• Added a work around to set the GPIO pin being used for audio output on ESP32-S3 boards low since Circuitpython is now defaulting pins high on those boards.
• Directory listings and environment variables are now displayed sorted alphabetically

PyDOS has been tested on the following microcontroller boards:
