cylondata#610: SampleArray util method replaced by using arrow::compu…

…te::Take and pass corresponding indices to it - changes from build to using std:vector and std:sort. Vector data is moved to an arrow::Buffer::Wrap (wrapper) that can be used by the actual arrow::Array (continued - adds call to WrapNumericVector function added by cylondata#615-cylondata#616)
