Integrate Wireguard

[ignoramous]

Blokada integrates with Cloudflare's BoringTun and that looks pretty straight-forward.

Wireguard's official cross-platform implementation is in golang (being rewritten in Rust?) and so the integration could be relatively simpler than with BoringTun.

The traffic would probably go from app -> vpn-tun -> tun2socks -> wireguard. Wasteful?

May be, the entire firewall and DoH implementation can be moved into wireguard instead?

I just wanted to say that a proper Wireguard integration will really help the Iranian people to circumvent the current internet censorship while maintaining their privacy by blocking Internet access of the apps and thus fulfilling one of Rethink's stated goals to bypass censorship.

What I mean by "proper integration" is that currently SagerNet/Matsuri's SOCKS5 for Wireguard doesn't work correctly in combination with Rethink's SOCKS5 in latest version, I don't know whether it's worth reporting when a Wireguard integration is in the works already.
