[doujindesu] add support

[iseeface]

Helloooo mikeee

So i just made extractor that support for downloading from doujindesu.tv :)

Implemented extractors:

• DoujindesuMangaExtractor
  Handles /manga/ listing pages, fetching all available chapters.
• DoujindesuChapterExtractor
  Handles individual chapter pages and direct non-chapter posts containing images.

Limitations:

• Only supports /manga/ and chapter pages.
  Other sections of the site are currently not implemented.

Testing:

1. Successfully tested locally on multiple scenarios:

• Manga with chapters

$ python -m gallery_dl -o browser=firefox --cookies "ddcookies.txt" https://doujindesu.tv/duplex-house-chapter-02/
.\gallery-dl\doujindesu\Duplex House\c002\Duplex House_c002_001.webp
.\gallery-dl\doujindesu\Duplex House\c002\Duplex House_c002_002.webp
.\gallery-dl\doujindesu\Duplex House\c002\Duplex House_c002_003.webp
.\gallery-dl\doujindesu\Duplex House\c002\Duplex House_c002_004.webp

• Manga without chapters (single post format)

$ python -m gallery_dl -o browser=firefox --cookies "ddcookies.txt" https://doujindesu.tv/chop-stick-3/
.\gallery-dl\doujindesu\CHOP STICK 3\CHOP STICK 3_001.webp
.\gallery-dl\doujindesu\CHOP STICK 3\CHOP STICK 3_002.webp
.\gallery-dl\doujindesu\CHOP STICK 3\CHOP STICK 3_003.webp
.\gallery-dl\doujindesu\CHOP STICK 3\CHOP STICK 3_004.webp

• Titles containing special characters (spaces, apostrophes, symbols)

$ python -m gallery_dl -o browser=firefox --cookies "ddcookies.txt" https://doujindesu.tv/the-hotties-good-at-football-chapter-01/
.\gallery-dl\doujindesu\The Hottie's Good at Football\c001\The Hottie's Good at Football_c001_001.webp
.\gallery-dl\doujindesu\The Hottie's Good at Football\c001\The Hottie's Good at Football_c001_002.webp
.\gallery-dl\doujindesu\The Hottie's Good at Football\c001\The Hottie's Good at Football_c001_003.webp
.\gallery-dl\doujindesu\The Hottie's Good at Football\c001\The Hottie's Good at Football_c001_004.webp

2. Output matches the intended directory and filename structure.
3. No runtime errors encountered in local testing.

Notes:

• When using:
  gallery-dl -o browser=firefox --cookies doujindesucookies.txt https://doujindesu.tv/manga/example-title/
  the extractor generally works fine, but Cloudflare challenge may still appear occasionally. I don't know if that's because of my internet provider or something else.

$ python -m gallery_dl -o browser=firefox --cookies "ddcookies.txt" --verbose https://doujindesu.tv/manga/yarimoku-hitozuma-to-matching-shite-sokuhame-sex/

I was a little unsure about dropping the extension checks on a4f7ae3a9f7c4b9bacb4e4ae7ee8a83424311ad5, but the ch.php API response is always a reliable set of <img> tags. Since the format is so consistent, i decided to just go with the cleaner approach.
