* added service to transfer Add-on config from options.json to config.toml

* added feature to get MQTT config from Homeassistant

current version is MVP. can run as Home Assistant Add-On, config.toml is automatically created from option parameters in the add-on configuration tab.

* fix pylance and flake8 warnings

* prepare building a ha addon

- move build script into root dir
- cp source files in addon build-tree

* ignore proxy source files in addon build tree

* move proxy source files in own directory

* remove duplicates source files from repro

* check for a valis SONAR_TOKEN

* rename add_on path

* prepare for unittests and coverage measurement

* move file cause of the changes pathname

* move the proxy dir to /home/proxy

* build addon with make now

+      For each GEN3 inverter, the serial number of the inverter must be mapped to an MQTT
+      definition. To do this, the corresponding configuration block is started with
+      <16-digit serial number> so that all subsequent parameters are assigned
+      to this inverter. Further inverter-specific parameters (e.g. polling mode) can be set
+      in the configuration block
+
+      The serial numbers of all GEN3 inverters start with `R17`!
