add UAVCAN Dronecode CAN connectors #2

It is very narrow on the end with the Dronecode CAN connectors but I think it will work out. I connected the 5V of the CAN connectors directly to the 5V IN of the Arduino MKR connector. Regarding the spec for this voltage I think this is the most useful connection.

Looking good :+1: :coffee:

Hi @aentinger I added a diode from CAN VCC to Arduino VCC. So the user can decide by placing this diode if he wants to couple these two voltage rails and in which direction the voltage should flow. Just like it is described in the dronecode spec.

I also added the option to use a different CS pin for SPI. Then two shields could be used with one Arduino for example to have redundancy for UAVCAN.

That's an terrific idea! Great feature @generationmake 🚀
