Fault reading in h-opc-cli.exe

[teowe]

Thanks for public the project, it's help me to much.

Your library is very good, but i found issue with return value in read command in h-opc-cli.exe (monitor command also)

Line 149 in Repl.cs Console.WriteLine("Value changed: " + o); //should be o.Value
Line 161 in Repl.cs Console.WriteLine(value);//should be value.Value

BTW, I'm not a developer so I have no idea to deal with GitHub. I just left Issue here.
