Support AmneziaWG

[smoore]

There is a legitimate need for a VPN that can work around enterprise SWG. I wrote my story here: https://forum.opnsense.org/index.php?msg=267146

It's also been mentioned that many hotels and other sites that hosts normal civilians impose restrictive policies that truly threaten legitimate work. I've stayed in hotel chains that WG doesn't work so I've used OpenVPN/tls-crypt on 443 to get to my console, but this workaround has aged and easy to catch.

AmneziaWG is one such solution (if the SWG doesn't blanket-kill UDP), but I agree, universal tools like wstunnel are longer-term solutions.
