Making GOnetstat faster

I needed a netstat library for some program in go. Problem is the only one that exists is very slow. So I challenged myself to make it as fast as I can.

I'm adding a branch for each faster version. In the readme of each version you can find its execution time.

Execution time

Original execution time:

PASS
ok      GOnetstat       0.955s

Current version execution time:

PASS
ok      GOnetstat       0.079s
