PDF issues: do not generate ProcSet array resources

[ronaldtse]

Metanorma generates ProcSet array resources. These were deprecated back in PDF 1.4 in the very early 2000s - please don't generate as they are a complete waste of bytes!

From #201

Currently, the PDF (for instance, rice-en.final.presentation.pdf) contains only these data:
/ProcSet [/PDF /ImageB /ImageC /Text]

From fop-2.8\fop-core\src\main\java\org\apache\fop\pdf\PDFResources.java:

        PDFArray procset = new PDFArray(this);
        procset.add(new PDFName("PDF"));
        procset.add(new PDFName("ImageB"));
        procset.add(new PDFName("ImageC"));
        procset.add(new PDFName("Text"));
        put("ProcSet", procset);
