Support CANopen FD (CiA 1301)?

[sveinse]

Have it been considered to add support for CANopen FD (CiA 1301)? Is it of interest to add support for it in this library, or would it better live in another?

The concepts are very similar, but there are protocol differences. E.g. EMCY have a larger payload, a new Universal SDO (USDO) protocol to mention two examples.
