Integrate the PCAN-USB PCANBasic.py Python interface for PEAK devices (and others). This will enable CAN interface tooling to work on Mac OSX.

This was merged to UAVCAN v0.5 branch. Rework that patch to work here.

You might be able to use it via Python-CAN as-is, like UAVCAN__CAN__IFACE='pcan:PCAN_USBBUS1'.

I'm not sure if Python-CAN works on macOS though
