[FEATURE] - Reduce the amount of location requests for untrusted WiFi auto-tunnel feature

[Mynacol]

Is your feature request related to a problem? Please describe.
The amount and frequency of location requests when using the untrusted WiFi auto-tunnel feature gets annoying. Modern Android shows an indicator each time it is requested. It clutters the privacy dashboard with so many location requests you cannot comfortably use it to track the location permission usages of other apps.

Describe the solution you'd like
Maybe use network change broadcasts to get notified by Android whenever the network configuration changes. This would limit the required location permission requests to exactly the times the network changes. (See #419 for some more details).

Describe alternatives you've considered
Preserve the status quo, it is functional and at worst only annoying.

Additional context
Past discussion was in issue #419, this one tracks the frequent location requests.
