Refactor discovery

[Darsstar]

First commit:

• test with 3.11 and 3.12
• require combined coverage from all versions to be 100% instead of individual Python versions, this allows sys.version_info < (3, 10) checks to be used in the code base.

Second commit:

• The main purpose is to speed up discovery.
• But is also provides similair functionality to #144.
  • The difference is this PR does not use the class name, but creates names entry points instead.
  • This PR allows for a list, instead of a single class/model. The Home Assistant integration could add a config entry to manage which inverter classes/models are enabled. During discovery it would then only pass those enabled inverter classes/models to solax.discover()
  • solax.discover() can also return a list of all inverter models/classes instead of returning the fist that succeeded. Which can be used by Home Assistant to have the user resolve such situations.

Third commit:

• Provides functionality to fix https://github.com/home-assistant/core/pull/107615 properly
  • x3_hybrid_g4 has a monlty reseting energy, which isn't supported by Measurement, but that can easily be added if desired.

Fourth commit:

• Adds inverter SN to the named tuple. Home Assistant could then use that instead of the dongle SN. Which would have the benefit of having only one entity if a broken dongle needs to be replaced.

@squishykid It took me longer to finish than expected. Hope you enjoyed your holiday! PS. I assume you are the one who started following me on Trakt :p

Nice! Do you also have patches for HA to apply your approach in the component?
