ARTA driver for turntable.

This script should be converted to a .exe and can be called by ARTA. It relays
the ARTA command to the DMX controller.

Convert to .exe:
    - pip install pyinstaller
    - python -m PyInstaller --onedir -w ARTAdriver.py
    - The resulting .exe will be placed in the directory "dist"
