implements terminal packets

Fixes the packety tests

implements very basic getting of input and sending them as commands to the server and printing responses

introducing flags!

adds a fairly interesting abstraction around packets and shit ... successfully authenticates or failes to authenticate

adds client struct

reading responses and writing them and stuff I guess

added dummy client code, moved the lib stuffs into its own directory

I think this puts it into one thing so it goes as a single packet ... this is probably not neccessary and should be undood

length was buggy, added another test

the test passes, yay!
