nwipe/src/create_pdf.c
PartialVolume a29cc3b543 PDFGen6 - further work on PDF certificate 
1. Fix @param in pdfgen.h, committed and accepted upstream
2. Added size of disk in bytes
3. When NVME drive show message "Not applicable" for HPA, DCO
4. Highlight status ERASED, FAILED etc with coloured ellipse
5. Added function help for nwipe_log (shows in hints in IDE)
