[Feature Request] Display option for a 'total chapters' Badge

[darktorana]

What feature should be added to Suwayomi?

An additional Display option, along side 'Unread badges' & 'Download badges' called 'Total badges'.
This would display the total number of chapters for that manga, based on the results already in the H2 database.

The data is in the database and can be easily fetched:

FROM PUBLIC.CHAPTER AS c
JOIN PUBLIC.MANGA AS a
ON c.MANGA = a.ID
WHERE c.IS_DOWNLOADED = FALSE AND a.TITLE = 'Martial Peak'
GROUP BY a.TITLE

Why/Project's Benefit/Existing Problem

Currently it is impossible to tell from the library window if a Manga is missing chapters without going into it.
If you have never read the Manga, then 'Unread' and 'Download' badge can be used if it matches (IE If you have unread 33 chapters, and downloaded 33 chapters, smart money says you have them all).
But if you've read part of a Manga then this no longer works.

IE:
Manga has 100 chapters
You've read 10 so 'Unread badge' shows 90
Downloaded shows 90 because you have the first 90 downloaded. Without clicking into that Manga you can't tell that there is 10 missing.
