New VI: "Get Default Data from Variant"

In the lvdata package there is a VI called Get Default Data from TD (that accepts a type descriptor input), but there's no equivalent (wrapper) for variant data input. A VI named "Get Default Data from Variant.vi" should be created and added to this project.
