Release v2.3.0

Finding 3: Add common.states enum maps to emsWorkMode, runningState,
dcCharger.runningState and plant.control.remoteEmsMode via ENUM_STATES_MAP
lookup in _createStateFromRegister/_createWriteStateFromRegister.

Finding 4: Import and wire PSS_WRITE_REGISTERS, PID_WRITE_REGISTERS,
AC_CHARGER_WRITE_REGISTERS — create write states and subscribe in
_createObjects(); handle pss.control., pid.control., acCharger.control.*
writes in onStateChange() (slave IDs: pssSlaveId||5, pidSlaveId||6,
acChargerId||2).
