Remove Crunchyroll simulcast calendar dubs

Removes the dub titles from the Crunchyroll simulcast calendar.

Somewhat recently, Crunchyroll expanded the amount of dubs they produce, adding multiple languages along with multiple animes every season. While this is great, the amount of dubs they produce is insane and takes up a lot of space in the simulcast calendar. This extension removes all the dubs from the calendar to have a pure subs only experience of it.
