SenseHat - test_joy.py on Pico

[mchobby]

Recurrent reading of Joystick position returns an OSError 5 exception on the Raspberry-Pi Pico.
This seems to be unpredictable.
Accordingly to MicroPython forums, OSError would be a NACK sent by the device causing the exception raising.

Remark:
At the moment, no workaround found for this issue. Trying to capture it with a try/except from SenseHat.py just lockdown the Joystick code execution on the Pico!
