[FR] mieru Proxy Protocol

Feature description

Thanks @enfein hiddify for suppor mieru, it is a good addition.

https://github.com/enfein/mieru

The principle of mieru is similar to shadowsocks / v2ray etc. It creates an encrypted channel between the client and the proxy server outside the firewall. GFW cannot decrypt the encrypted transmission and cannot determine the destination you end up visiting, so it has no choice but to let you go.
