[Ovmsdev] Digital Speedometer

I think there are 2 reasons you get the occasional amps display:
When we use the modem, there is a delay loop, and we don't do the periodic speedo message transmission while in that loop. This is, at worst, once every minute or so.
Occasionally, the car is going to win.
At aggressive factor 5, I find it acceptable. The AMPS display is pretty rare.
This can never be 100% perfect (unless we can find some way to suppress the car messages, which I doubt).
P.S. Soapbox: this does show how easy it is to do. Tesla could do this _very_ easily in their firmware and that would be perfect.
