Option to track volumes

[nephthys11]

Describe your suggested feature

Some mangas in my library are sorted as entire volumes instead of chapters, i.e. a "chapter" in the app is a volume with multiple chapters.

This is an issue when using trackers as they only track chapters. I suggest adding an option whether to track volumes or chapters when adding the tracker.

Other details

This suggestion is similar to Tachiyomi Issue #8143
