Generate a PDFMARK file for Ghostscript >= 9.14, for PDF/A conversion

pdfmark is an extension to the Postscript language that describes some PDF
features like bookmarks and annotations. It was originally specified Adobe
Distiller, for Postscript to PDF conversion:
https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdfmark_reference.pdf

Ghostscript uses pdfmark for PDF to PDF/A conversion as well. To use Ghostscript
to create a PDF/A, we need to create a pdfmark file with the necessary metadata.

This takes care of the many version-specific bugs and pecularities in
Ghostscript's handling of pdfmark.

|dd�|S)a�Create a Postscript pdfmark file for Ghostscript PDF/A conversion

    A pdfmark file is a small Postscript program that provides some information
    Ghostscript needs to perform PDF/A conversion. The only information we put
    in specifies that we want the file to be a PDF/A, and we want to Ghostscript
    to convert objects to the sRGB colorspace if it runs into any object that
    it decides must be converted.

    See the Adobe pdfmark Reference for details:
    https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdfmark_reference.pdf
