[NTG-context] option for printing range

Hans, would it be possible to add an key to \setupinteractionscreen that implements the /PrintPageRange key in the /ViewerPreferences dictionary (https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.... For example, "\setupinteractionscreen[range={2, 4-7, 10}]" should add the "/PrintPageRange [1 1 3 6 9 9]" in /ViewerPreferences. (BTW, the key name is the first one that came to my mind.) This is extremely useful to help the user to print only the required pages and not the whole document (which may be required only for viewing purposes). Many thanks for your help, Pablo -- http://www.ousia.tk
