Implemented optionally extending CAN IDs within iso15765 #51

Before this change, all CAN frames were sent in extended-ID mode, even if the ID was less than 0x7ff. This caused undesired behavior on vehicle and bench testing using PCAN-USB tools where the receiving module ignored extended-ID CAN frames.

After this change, the iso15765 implementation by default does not extend the CAN IDs unless they exceed 0x7ff. This can be overridden by an API parameter: "force_extended".

Rebased to master (not sure if this was necessary).
