Mandown

Feature changes
- **New source:** https://bato.to! (#85)
- New process option: `webp_to_png` — this option converts all image files to PNGs in case the source site uses WEBPs, as they aren't supported in EPUBs.

Bug fixes
- Crawled image links that were broken no longer crash Mandown (bd09c65)

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
