Update so it works on modern rootless Jailbreaks

With the introduction of rootless Jailbreaks with iOS 15 almost all tweaks made before iOS 15 became broken as a result. That would mean that updating the tweak requires recompiling through Theos and potentially even additional fixing. Personally I could offer several test devices if that's a barrier. Jailbreaking is still semi profitable even which is funny. Would be awesome seeing the tweak on iOS 15+ though that's up to you :)
