Custom media covers for anime

[ttiamus]

Is your feature request related to a problem? Please describe.
When using custom media covers, it bases the covers and overrides on the library type. Since anime is managed as "Shows" it causes duplicate and misleading covers.

Describe the solution you'd like
A way to define a library name in the overrides instead of the collection type.
Example

@import url("https://cdn.jsdelivr.net/gh/lscambo13/ElegantFin@main/Theme/assets/add-ons/custom-media-covers-latest-min.css");

:root{
--colorOverlayAnimeCover: rgb(39, 68, 185);
--urlAnimeCover: url(https://awesomeAnimeArt.com/nice.jpg;
}

Describe alternatives you've considered
I looked at trying to use collections for this, but seems difficult to manage. Standard for Anime libraries seems to be marking them as "Shows".

Additional context

Side note - The theme looks great! Thanks for the hard work!
