Newer models of the APH Refreshabraille have optional HID support. The Baum VarioUltra and Pronto! have USB HID and no USB serial.

…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.
