Port Arianna to Foliate-js

Arianna reader uses the epub.js, which is no longer actively maintained. This creates a challenge as the epub.js may not be able to keep up with the evolving standards and new changes. To address this issue, the proposed solution is to port Arianna to Foliate-js, which is an actively maintained epub renderer and has more features compared to epub.js and is used by the Foliate ebook reader.

The problem that this project aims to solve is the need for a reliable and up-to-date epub rendering solution for the Arianna ebook reader.
