usage: scripts/debug.sh start|stop [--platform vscode|pycharm]

Requires the device-side debugger package to be present in the app's Python
runtime: `debugpy` for vscode, `pydevd-pycharm` for pycharm. If it is not
installed, add it to "requirements" in plugin.json so the app's pip
controller installs it on next load.
