Create a basic server using TCP

The server should ues net.Listen to listen on port 8080.

Remember to close the listener using defer.

Remember that from the "net" package you first need to LISTEN, then you need to ACCEPT an incoming connect.

Now write a response back on the connection.

Use io.WriteString to write the response: I see you connected.

Remember to close the connection.

Once you have all of that working, run your TCP server and test it from talnet (talnet localhost:8080).
