	Turns out when I removed the `unwrap`s in 92f8f57b76b32c3d3e52d4b61dcdf25969f47ab7, the `return`s I added to the `match` expressions caused the loops to exit early without iterating over all the objects in the PDF. Remove the `return`s and fix up the expression return types to get URLs printing again.

2019-11-01	Find the PDF object that URLs are stored in	Teddy Wing
	Thanks to plinth (https://stackoverflow.com/users/20481/plinth) on Stack Overflow, learned that URLs are stored in /A entries in a PDF: > To get the link to go somewhere you'll need either a /Dest or an /A > entry in the link annot (but not both). /Dest is an older artifact for > page-level navigation - you won't use this. Instead, use the /A entry > which is an action dictionary. So if you wanted to navigate to the url > http://www.google.com, you would make your annotation look like this: > > << /Type /Annot /Subtype /Link /Rect [ x1 y1 x2 y2 ] > /A << /Type /Action /S /URI /URI (http://www.google.com) >> > >> https://stackoverflow.com/questions/19492229/add-a-hyperlink-into-a-pdf-document/19496996#19496996 To extract URLs, find the /A objects and get the text value of their `URI` fields.
