Add option DataMatrix

[Rondinelly]

If it to interests you, I implemented the DataMatrix barcode writing for ZPL according to the Manual

Follow example:

var page = new List<byte>();
page.AddRange(ZPLCommands.ClearPrinter(printerSetting));
page.AddRange(ZPLCommands.DataMatrixWrite(10, 10, ElementDrawRotation.NO_ROTATION, 10, "Test"));          

 Print(page, printerSetting);

Result:

There were also some indentations due to the Visual Studio.

If need some adjustment, I'm ready to do it.
