Picoware - v2.0.0

This is an update to the MicroPython version that adds USB video streaming to your computer with a desktop viewer, an embedded JavaScript engine with JS modules (draw, wifi, http, and more) runnable within Picoware (Library -> Scripts), a ~27% FPS boost on PicoCalc from southbridge and LCD optimizations, and an mp3player app!

Changelog:

• Added mjs C module with
  • draw, storage, time, log, pin, http, system, input, wifi, settings, uart, and math JS modules
  • a JS MicroPython class (picoware.system.js) with run and exec methods to execute a string or load a script from storage
  • a menu option in the Library section called Scripts that lists .js files in picoware/scripts/* and executes them on-click (with the result logged)
• Added usb_video C module that sends frames over USB when connected:
  • USBVideoStream class (picoware.system.usb)
  • USB Stream toggle in settings (Library -> Settings)
  • Python GUI to view the stream (python tools/usb_video_viewer.py)
• Increased system FPS on PicoCalc by about 27% (from 23.82 to 30.30 on the Pico2W in our tests):
  • increased southbridge baudrate from 10 to 100
  • doubled LCD chunk size
• Updated audio driver to expose AudioInfo class (picoware.system.audio.AudioInfo) and correct mp3 seeking
• Added load_module method to AppLoader class for testing in ThonnyIDE
