[REQUEST] Sort by Update Count in 0.8

[avora97]

Description Allow for Library to sort by Update Count as well as total Unread Chapters, similar to 0.7.

How would it improve the App? Added user functionality. It would allow for users to be able to view which works have the most/fewest unread updates at the top of the library and bypasses source/app issues that lead to a full reset of the chapter list (i.e. issues that cause all of a work’s chapters to be marked as unread), which is a common issue with certain sources and occasionally when migrating between sources. It also just makes sense to be able to sort by the number in the bubble attached to a work in your library.
