Example adding a VBA macro to a workbook.

* An example of adding macros to a libxlsxwriter file using a VBA project
* file extracted from an existing Excel .xlsm file.
* The utility from the libxlsxwriter examples directory can be
* used to extract the vbaProject.bin file.
* This example connects the macro to a button (the only Excel/VBA form object
* supported by libxlsxwriter) but that isn't a requirement for adding a macro
* file to the workbook.
