…ra and Pronto! when connected via USB.

Also, the Baum driver now uses hwIo.Serial for serial communication, thus avoiding polling every 50 ms, which should slightly improve performance.
Fixes #5609.

@jcsteh jcsteh Enhanced I/O for braille displays:
* hwIo.Serial extends pyserial to call a callable when data is received instead of drivers having to poll every 50 ms.
* Data is written to thread-safe braille display drivers in the background, thus avoiding blocking the main thread.
* hwIo.Hid provides support for braille displays communicating via USB HID.
