Code cleanup

[Xitee1]

• Improve the overall python code quality by running black formatter and fixing some variable naming.
• Added option to hacs.json to show readme instead empty info in the store
• (Temporarily) disabled an warning that massively spammed the HA logs even tough everything is working (the logs were so big that when loading the HA logs in the webinterface my PC with 32GB RAM ran almost out of memory 😄). Needs further investigation.

I hope that this gets accepted, seeing semicolons at the end of an line in python and mixed naming schemes in a single name just hurts 🥲 (Please don't take that personally, but this should get fixed).

If this gets accepted I will make further changes to make further overall improvements.
