Add support for booklet printing
I was looking at printing a 16 pages document as 'booklet' (2 pages per sheet of paper, printed on both sides, and the pages are ordered in such a way that I can fold the printed stack and I get a proper page 1, 2, 3, 4, ... sequence). I was happy to find a hit in gnome help for that https://help.gnome.org/users/gnome-help/stable/printing-booklet-duplex.html.en , and then disappointed that the instructions tell me to manually order the pages "Type the numbers of the pages in this order (n is the total number of pages, and a multiple of 4): n, 1, 2, n-1, n-2, 3, 4, n-3, n-4, 5, 6, n-5, n-6, 7, 8, n-7, n-8, 9, 10, n-9, n-10, 11, 12, n-11…" It would be nice to have some native support for this rather than needing to do this.
