S allius/issue128 (#130)

* set Register.NO_INPUTS fix to 4 for GEN3PLUS

* don't set Register.NO_INPUTS per MODBUS

* fix unit tests

* register OUTPUT_COEFFICIENT at HA

* update changelog

* - Home Assistant: improve inverter status value texts

* - GEN3: add inverter status

* on closing send outstanding MQTT data to the broker

* force MQTT publish on every conn open and close

* reset inverter state on close

- workaround which reset the inverter status to
  offline when the inverter has a very low
  output power on connection close

* improve client modified
- reduce the polling cadence to 30s
- set controller statistics for HA

* client mode set controller IP for HA
