Title: Collect some stats

This PR will set Panel up to collect various stats about breaker activity.

- [x] Publish trip/reset counts to a Statter interface
- [x] Replace `OnTrip` and `OnReset` callbacks with a channel based event stream
- [ ] Make the stream a little more robust in the case of absent/blocking listeners
- [ ] Possibly replace Panel's callbacks with event streams?
