Custom notifications on iOS 13+

Somewhat customizable settings page! I'll be adding a scheduling option sometime in the future :)

Probably works on lower versions but it is untested so try at your own discretion!

Not much but its honest work :3

Also credits to Nepeta's work on Notifica for helping me in figuring out how to send notifications without the use of libbulletin! (It was a pain lol)
