Add to HACS plugin repository

[cociweb]

Hello @dreimer1986,

Unfortunatelly, the original author of this repository is passed away and his repo is also removed from the HACS plugin library, could you please request a listing for your, as a replacement?

Thank's in advance.

I dont know if this is a good idea... I don't plan to maintain it in the future. I made my own replacement as the addin now fails to modify the sidebar. I have to think about it.
Btw, https://github.com/dreimer1986/yourname_card_mod/blob/master/README-script.md this is mine. Cleaner and easier to fix stuff AND way more difficult to ever break things.

please edit readme.md and removed HACS install instructions.
