 * Anti-Packet stacking

 * No need to stringify or parse JSON's, the data you send is the data you receive, no annoying buffers
 * No limits from tcp

+### Connected Sockets and All Sockets:
+There is a built-in, auto updating array with all the connected sockets and every socket that is and has been connected (In its runtime, a restart would reset this)

+let arr: connectedSockets = TCPServer.connectedSockets;
