    WireGuard: implement decryption with PSKs
    
    This imposes an additional requirement on the key log file, PSKs are
    only linked to the most recently seen ephemeral key. This means that the
    key log might contain duplicate PSK lines, but at least the dissector
    won't have to try all keys and thereby save CPU time.
