Move to using pyusb instead of custom HID code

[peircej]

pyusb is available and easy to install on all platforms as far as I know.
In particular this would immediately allow compatibility with linux I think?

(I don't personally know much about USB protocols though)

Might be time to make this move. ioLabs bboxes are no longer working in PsychoPy 1.83.x (on mac at least). One major change as compared to 1.82 is (on mac) the move to 64-bit python. So moving away from the custom HID code might fix that (as well as support linux).
