New:

- Added system (Android 13+) language chooser in settings (#56, thanks @Aga-C).
- Added importing and exporting app settings (#51, thanks @Hirdaya-Shrestha).

Fixed:

- Using localized unit strings instead of hardcoded English ones (#63, thanks @Hirdaya-Shrestha).
- Rewritten live updates to use NotificationCompat, to ensure it works well with API 36.
- Turned off force refresh of battery data in OS in the Advanced tab, which could cause issues with some battery drivers.
