mpy-tool.py is not Python 2.x compliant #1983
Description
A build using persistent bytecode fails with
CC build-PYBV10/pins_PYBV10.c
MPY scripts/fonts.py

This can be fixed by mandating Python3 in py/mkenv.mk but then make deploy fails unless I reinstate Python2. This is because (as I understand it) the usb.core module supports only P2.
