What's Changed

New features

• This release adds event handling. The webserver can now display a list of events that have triggered in the system. For instance anything out of the ordinary; cell overvoltage, overheating, CAN failures etc. all get logged to the event list. The events are also stored to EEPROM for an additional layer of security. Event handling makes troubleshooting a problematic situation much easier. Massive thanks to @Cabooman for implementing most of it 🙌

The event log can show you how many events have occured, when the last event of this type happened, severity of event and data. Events get stored to EEPROM, so if you later on power on the board, it will spit out the last events via serial on bootup. How neat is that? 👍

Note for devs: Events should be used for further development of all battery handlers, since it centralizes the writing of BMS status and handling of LED color and serial printouts.
