[FEATURE] Highlight current library in context of series/book

[aaronleopold]

Is your feature request related to a problem?

When I am accessing a series or a book, I would like the library to be highlighted in the sidebar

Describe the solution you'd like

It is fairly trivial to determine what library I am browsing within the context of a series or a book. The trickier part will be sending that information up the tree. I'd say a viable option is to create a hook specifically designed to sus the library based on a few URL patterns
