[WireGuard] auth-only wireguard

[Jehan Tremback]

Are there any plans, or would you even consider, adding an option to
WireGuard to disable encryption, and only authenticate packets? I'm
assuming that an authentication-only mode would be significantly faster
(maybe I'm wrong though). My use-case only needs auth, so if I were to
use WireGuard, the encryption would be redundant.
