[Ovmsdev] Scan and discover process for 29bits PID

support for CAN extended frame mode hasn't yet been implemented on the 
RE scanner or the OBD poller.

As I wrote before, that's totally rare in vehicles, there wasn't any 
need to support this up to now.

If you need it, you're welcome to implement it. But I doubt you need it.

You can possibly check by sending some strategic CAN extended frames 
manually, see command "can can1 tx extended".
