Feature Request: Disable Color Inversion Option

[rmateu]

Understand how this could be useful to many, but for some reason most of my icons fall just on the threshold and it inverts incorrectly.

Could an option be added to disable Color Inversion?

Thanks for the plugin!

This cannot be influenced by the plugin code as easily, a better solution would be if you add the the following css snippet:

.link-favicon[data-is-readable-a-a="false"] {
	filter: unset;
}
