v3.0.0

This release follows a different approach and is incompatible with the initial setup of this project.

When multiple batteries are connected through their RS485 port it is possible to query each device, including the master via the CAN port – without multiple masters on the bus as usually the inverter is the master when reading the BMS through RS485 instead of CAN.

This means, that one has to split the CAN port to pass the CAN connection to the inverter and the RS485 onto the next pack on the master pack and also split each slave's CAN port to connect it to the previous and next pack.
