This function recieves a command from the Autobox with the CAN ID of 0x501.
with format of:
data[0] = target state
0x0 STATE_INACTIVE | disconnect power to the ESC of powerground. Send it to return the mvbms to idle/monitoring mode. If data[1] != 0 -> assume bad CAN message.
0x1 STATE_READY | conneect power to the ESC of powerground and but with no PWM signal. If data[1] != 0 -> assume bad CAN message.
0x2 STATE_ACTIVE | activate powerground at (data[1]) percent. If data[1] > 100 -> assume bad CAN message.
