Tun-azumi_V1.5

Changed transfer method which caused problem in "couldn't write to tun" error and was causing the tun to drop connections after some time.
Removed Smux to be studied further in my online games. [ It will be added in a later version]
other options are intact.
added keepalive

Tun-azumi_V1.41

Added worker: -worker or default based on CPU cores
Add buffer size increase for worker channels.
Added concurrency handling func & removed ping interval and service name. Instead, I use another simple service with bin bash script to restart services based on server unreachable error.
Fixed some connection bugs
Added tcp keep alive : -keepalive true
Added keepalive interval : -tcp-interval 15
I am still testing this in the game to find potential problems.
I am going to combine it with Vxlan next update.
I am still undecided on encryption and compression.

Tun-azumi_V1.4

added nonce & sha 256: usage -key
added both upx compression and non-compressed
amd64_upx.zip for compressed version
amd64 for non-compressed version

Tun-azumi_V1.3

added xtaci smux
added tcpnodelay
added heartbeat and heartbeat interval
removed retry connection if server disconnected and instead added ping interval and service reset upon failure
added logrus
still having problems with optimizer & ufw
next update : IPSEC or Chacha20 , Worker
maybe toml config file
there maybe still some hidden problem which i am not aware of.
I am using this for personal use so I don't guarantee anything for commercial usage.
This is a learning project

Tun-azumi_V1.2

Better handling of errors
removed unnecessary logs for better performance
added verbose false/true for enabling or disabling logs
