V490 / all-in-one monitor board hang and passive balance enabled #262

Describe the bug

I have had a problem with an all-in-one. Communication through module 2 has failed. The red leds were fixed, without flashing. Burning energy. Unbalancing the 36S batteries. Does the STM32 software have any watchdogs? To restart the module after a period of time without communication.

I've added in a watchdog timer to automatically reboot the module should this scenario occur where the CPU appears to hang without communication.

This isn't the final solution to the underlying problem, but does help overall and prevents waste of energy.
