Generate PDF/A compliant document

[Feature]

Hi there,

I have integrated jsPDF for a project but now that I realised its a strict requirement from the customer to have pdf file as PDF/A compliant which jsPDF doesn't generate. PDF/A is basically a plain PDF with fonts embedded in file itself. And also a min of pdfVersion = '1.4' should be used. Currently jsPDF genereates files of pdfVersion = '1.3'.

Is there a way to set the pdfVersion? And also genereate PDFs with PDF/A compliance?

More info on PDF/A - https://en.wikipedia.org/wiki/PDF/A#:~:text=PDF%2FA%20is%20an%20ISO,to%20font%20embedding)%20and%20encryption.
