[Android 10] Dark Mode at sunset

Determines when the next sunset/sunrise occurs, waits until that time, and attempts to set the "Dark mode" setting on Android 10 to the respective mode. Doesn't work on my phone (Nokia 7.2), no matter what permissions I play around with. Maybe it'll work for you. Let me know if it works for and if so, any bugs/feedback!
