Shorten PrusaSlicer output filenames for all default printers

fix_output_filenames.py

""" Shortens output filenames for all printers in prusa config folder.
Will turn filename into: {input_filename_base}_{nozzle_size}_{printing_filament_types}_{print_time}.gcode

Place this file in your PrusaSlicer config folder (Help->Show Configuration Folder) and run it with python.

Make a backup first.
