feature/include-double-subscription-logging

[JaapBosheuvel]

For the OMNT app we wanted to add the feature to log for both subscriptions. The following features are implemented to enable this feature and some small improvements to make it not required to restart the app before changes are applied:

• first startup now contains permission check that only runs initialization after all permissions are granted (fills ui immediately)
• added 'all subscriptions' option (set as default) for set subscriptions option
• subscriptions can now be changed dynamically during runtime and during logging, which also immediately affects UI (no reboot required)

TODO

• signal strength logging still compatible for only one subscription;
• neighbour cells unidentifiable and should be sanitized with mcc/mnc of registered cell (can still be done manually due to logging is ordered e.g. for 20416 and neighbour cells enabled then following cells without mcc/mnc are logically its neighbours until we see another cell with mcc/mnc)
• clean up version checks, a lot of evaluation on versions below minimum sdk can be removed
• clean up permission checks, added some missing permission annotations that could be replaced with requirespermission annotations
