Add support for roman numeral page numbers (ex. ii, iv)

[JustinDokumen]

Currently, page numbers are parsed as ints, leading this case to the fallback option

Hi @JustinDokumen, thanks for reporting this! The fix for Roman numeral page number parsing is now in progress via #173.

I've tested locally with a few sample PDFs and everything looks good on my end. Could you share the PDF file that triggered this issue? It would be great to verify the fix works on your specific document before we close this out.

Thanks!
