feat(src/en): New source: Kiutaku (#19445)

* feat(src/en): Create Kiutaku base

* feat: Implement popular entries page

* feat: Implement latest updates page

* feat: Implement search

* feat: Implement entry details page

* feat: Implement chapter list page

* feat: Parse page list

* chore: Add source (fav)icon

The source doesn't seems to have a logo, so I'm considering the favicon used by
the site as their icon.
