📄 Description

This extends the realm of USE_FMEMOPEN to all temporary files, which is accomplished by using open_memstream. It also adds two new workbook options, output_buffer and output_buffer_size, to allow outputting to a buffer when filename is NULL. This allows the library to be used without writing to the filesystem.
