QuickSwitch v3.3.0

Note, this update will reset the current provider

• better support some LG devices on Android 9
• allow installation on MIUI 12.5+ (oops forgot the check was there)
• remove sepolicy rules as they didn't help most of the time
• increase overlay priority again
• format scripts to be more readable
• the QuickSwitch app will now correctly specify Android 12.1 instead of 12 where applicable
• change module ID to quickswitch, order has been restored
• for module developers who check for the modID, I'd recommend instead looking for the /data/adb/modules/**/quickswitch binary instead
• update README to better explain the modules functionality
• update the modules update-binary because it was 2 years outdated xd
