[Feature Request] Trigger StrongAuthTimeout based on "home" WLAN

[ypid]

For a different use case than #11, it would be useful to also support triggering the need for StrongAuth when the user is connected to their home network. The simplest test would be WLAN SSID and MAC address, but a stronger, additional one would also be useful for example ssh-keyscan. Complexer tests could potentially be offloaded to Termux.

The logic of StrongAuthTimeout normally done by Android would need to be moved to this app so that a timeout could still be configured. The user should not be asked anytime they try to unlock at home.

This is a cool idea. ssh-keyscan would work well, although it would be good to combine it with something else so that the app didn't think it was at home when I connect to VPN.
