Mandown

Feature changes
- **New source:** https://comixextra.com! (#82, 80)
- This source has some broken image links that Mandown may stumble over
- When an image link 404s, Mandown now continues and ignores it for the current chapter instead of crashing

Bug fixes
- Update Manganato to support their new domain (chapmanganato.com → chapmanganato.to)
- Improve error messages

Bug fixes
- Upgrade to Comicon 1.1.0, which now supports slugifying titles it converts (77)
- Rename `--profile` from `-r` to `-o` to avoid the conflict with `--remove-after` which is also `-r`

Bug fixes
- Avoid creating invalid folder names by slugifying first (cbfca029e5155b18f81bfe46cacb067d81bf7f48)

Feature changes
- **New source:** <https://www.kuaikanmanhua.com>! (#75)
- `mandown.save_metadata(comic: BaseComic, path: Path | str) -> None` is now exposed in the API to save a comic's metadata to the filesystem.

Feature changes
- New source: https://comicfury.com! This also works for any comic hosted under its subdomains, `thecomicseries.com` (e.g., https://talesofelysium.thecomicseries.com)
- The progress bar now shows the current chapter being downloaded instead of showing it after it is downloaded

Bug fixes
A bunch of updates to a couple of sources from automated testing.

- misc: finally updated `mandown --version` from 1.3.4 to 1.6.1
- mangadex (en): all genres are now properly included
- webtoons: genres are now properly filtered
- blogtruyenmoi: description and author are now correct
- manhuaes: migrated to manhuaaz.com, but both links should still work
