Support more formats (#112)

Browse source 
* Added support for FB2 book format

* Add support for CBZ files by introducing a `ReaderDocument` abstraction.

Key changes:
- Defined `ReaderDocument`, `ReaderPage`, and `ReaderTextPage` interfaces to provide a unified API for different document types.
- Implemented `PdfDocumentWrapper` and `CbzDocumentWrapper` to handle PDF and CBZ files respectively.
- Updated `PdfViewerScreen`, `PdfPageComposable`, and `MainViewModel` to use the new unified document interfaces.
- Added CBZ file type detection and cover generation logic.

* Add support for CBR and CB7 comic book formats

- Add `me.zhanghai.android.libarchive` dependency to support RAR and 7z archives.
- Implement `ArchiveDocumentWrapper` using `libarchive` to handle CBZ, CBR, and CB7 files uniformly, replacing the previous CBZ-only implementation.
- Update `MainViewModel` and `DocumentFactory` to recognize and process `.cbr` and `.cb7` extensions and their associated MIME types.
- Add support for extracting and caching cover images from CBR and CB7 archives.
- Update UI components (`HomeScreen`, `LibraryScreen`, `AppNavigation`) to handle the new comic book file types.
