v3.0.0

Add experimental KCPTUN support.

KCPTUN should run as a plugin server of shadowsocks server.

Example:

Run a KCPTUN on your server, listening on port 53, redirecting to shadowsocks port 8388:

sudo kcptun -l :53 -t 127.0.0.1:8388 --crypt none --mtu 1024 --sndwnd 1024 --rcvwnd 1024 --mode fast --nocomp

Then the parameters for the client is:

--crypt none --mtu 1024 --sndwnd 1024 --rcvwnd 1024 --mode fast --nocomp
