In this version, we have fully rethought the XLSX_Range_Values_Set command.
It is now far quicker than previously.

We have also update the XLSX_Util_ExportData command for:
- more speed
- UTF-8 support

We fixed a memory leak.

And at last, we added a new XLSX_Range_Value_Set command dedicated to add single value in one cell.

 

Thanks a lot to Bernd Niggemann. He is in great help and good advices for optimizing things.
