suggest to add the offset about booky HOT 3 OPEN

Adding feature to handle page count offset (aka the difference between printed page numbers and the actual page numbers per the published book title) -- would be wonderful. I stopped using booky as it does not handle this feature and reverted back to use jpdfbookmarks, https://sourceforge.net/projects/jpdfbookmarks/

In Jpdfbookmarks, after loading the TOC
Expand all bookmarks (Ctrl + E), select all of them, then go to Tools > Apply Page Offset
Enter the first pages that outmatch the page number in the TOC

Here is how you can add offset

https://github.com/SiddharthPant/booky/blob/d64f4571fdeae9660173ada6e2a95cd8aff4a8f9/booky.py#LL16-L16C41

pageNo = line[commaIndex + 1:].strip()

change this with

offset = 23
pageNo = str(int(line[commaIndex + 1:].strip()) + offset))
