sync fail for protonvpn sync

[lestofante]

The sync fail at

thread 'main' panicked at vopono_core/src/config/providers/protonvpn/openvpn.rs:205:40:
Could not find code in map: ps

this seems to work if i select SecureCore instead of normal Plus server.
Mayeb it should be a warning rather than a Panic?

Thanks, it seems the issue is the addition of the Palestinian Territories Plus servers, which we don't have in the hardcoded map.

We should fix that (adding them here https://github.com/jamesmcm/vopono/blob/master/vopono_core/src/util/country_map.rs#L5 ), and the unwrap here https://github.com/jamesmcm/vopono/blob/master/vopono_core/src/config/providers/protonvpn/openvpn.rs#L204 (we can just leave the country code if there is no good mapping).
