allow --start-page and --end-page to be relative to end of chapter

The idea

It would be nice if one could download just the last page, or the last 3 pages, of many chapters. But I'm not sure how to look up how many pages there are in each chapter, which shouldn't really be necessary anyway. In python you can do my_array[-3:] to get the last three elements, and in this case something similar could be done if you set --start-page to -3 and --end-page to -1.

Why this feature should be added to the app ?

Sometimes the last page of a chapter has funny notes from translators. There are likely many other use cases.

Uhmmmm looks complex to me, but i will try to experiment it first, if it's works then it will be implemented. Thanks for the idea 👍

Works great, but is this also in the latest released version?

Sadly no, this isn't available in latest stable version (v2.10.3). It's in development version only and it will be released in v3.0.0.
