expose CAN FD support

[droogie]

Consider exposing CAN FD support as an option, I quickly added it locally by changing the following:

diff --git a/caringcaribou/utils/can_actions.py b/caringcaribou/utils/can_actions.py

     def bruteforce_arbitration_id(self, data, callback, min_id, max_id,

and then adding this to my .canrc

fd = True
