[FR]: Support State Badges (like the mushroom template card does)

[roderik-maker]

Is your feature request related to a problem? Please describe.

I want to match the style of your card to the mushroom cards in my dashboard but I am missing the option to add a small badge on the top right (like the mushroom template card offers)

Describe the solution you'd like

The option to configure a state badge (color and icon) that (when enabled) is displayed on the top right corner of the the elements icon/picture.

Something like this:

Describe alternatives you've considered

Custom button card and/or MANY lines of card_mod css injections but it's not elegant nor robust, loads slowly, and sometimes jumps around.

Additional context

I also fully understand if this is too much work or not the desired direction for this project. Either way, thank you for this awesome project!
