       This utility is used  to extract the VBA project binary from an Excel 2007+ xlsm file. The VBA project
       can then be added to an Excel::Writer::XLSX file to enable it to have macros.

       An "xlsm" file is a version of an Excel "xlsx" file that contains an additional VBA project binary file.
       The "xlsm" file format is a collection of mainly XML files in a ZIP container.

       The extracted VBA project is an OLE Compound Document in binary format. It is named "vbaProject.bin" and
       is generally located in the "xl" directory of the "xlsm" file.

       See the "add_vba_project()" section of the  Excel::Writer::XLSX documentation for more details.

       Note: you can also extract the VBA project from an "xlsm" file using the standard Linux "unzip" command:

           unzip -j macro01.xlsm xl/vbaProject.bin

       On Windows you can use any suitable Unzip application.
