[Feature] Add support for connecting to hidden networks

[hhvrc]

This would require specifying the BSSID in the connect command and requires some way to store these in the config together with normal network credentials

[LucHeart]

We should not do this via BSSID, this is not common. We should do it by specifying SSID and password. The main issue is probably it going by the scans if a network is available or not.
