PyBasic SOUND, PyDOS quoted arguments
PyDOS - added support for quoted arguments (files with spaces in names can now be used)
- modified copy command to use less memory and reduce the memory allocation errors
- tweaked directory command so it doesn't blow up when accessing a drive mounted through the new mpremote service
mpremote mounted drives appear to have a very different file system and don't currently work with most PyDOS commands
PyBasic - added the sound command. A speaker circuit must be connected on GPIO 20
External DOS commands:
diff - performs file comparison (FC)
lcdprint - display a message on an I2C LCD screen (https://www.microcenter.com/product/632704/inland-16x2-i2c-lcd-display-module)
(lcd2004.py support library missed the release but is posted to the main branch)
sound - outputs a sound to the speaker circuit connected to GPIO 20 (sound freq,duration,volume)
