Kavita support

[rourunisen]

> Lightning fast with a slick design, Kavita is a rocket fueled self-hosted digital library which supports a vast array of file formats. Install to start reading and share your server with your friends.

Kavita would make it easy to keep my books and comics in a central place without much trouble. It would be really great if it were easy to install on HexOS. I don't know if book and comic library is already covered in the list of curated apps but this would be a great option.
