Modbus controller class.
Each instance handles the modbus commuinication for all sensors with the same modbus address
all sensor items (sensors, switches, binarysensor ...) are parsed in modbus address ranges. when esphome calls ModbusController::Update the commands for each range are created and sent Responses for the commands are dispatched to the modbus sensor items.
