Kicker Overvoltage Lockout Behavior

[guyfleeman]

Kicker overvoltage lockout behavior currently has some quirks that should be addressed.

1. Kicker errors are not reported upstream (either at the kicker or control firmware level)
2. Kicker high voltage measurements are not filtered
3. Kicker has no mechanism to unlatch errors

2 and 3 are interacting negatively. Occasionally it seems measurement occurs when there's a small spike (probably on kicks). The target voltage is 182, and the over voltage lock out is 190, so ~4% error. I think there are a few options to solve this, but they need careful thought. We could bump the lockout voltage, but we need to make sure it below 200V enough to stop charging before we cross 200V based on the simulated or observed charge rate. Another option might be to filter measurements (we should do this anyway at least for the value sent upstream), but again we need to make sure the filter delay doesn't mean we stop charging too slowly.
