[evince] Open PDF from URL directly [feature request]

[Lampshade <lampshade poczta fm>]

I would like Evince to be capable of downloading PDF from URL and open it:

1. when I type in evince and URL in command line. Example:
$ evince 
https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf

2.  GUI method:
Open -> (Open Document windows) Other Locations -> Enter 
"https://hwpi.harvard.edu/files/torman/files/sample.pdf"; in "Connect to 
Server" field -> Click open

Rationale:
I often surf the Web and find unknown (for me), potentially interesting 
PDF documents. Built-in browser PDF viewer can't render substantial 
number of PDF documents correctly, so I must open them in stand-alone 
PDF viewer such as Evince. Desktop web browsers have a feature to 
download PDF file to temporary directory then execute external program 
to display them. However many things may interfere with/prevent that 
such as sandboxing tools (firejail), security features of package 
deployment managers (Snap) or MAC (Mandatory access control) policies. 
User may also prefer to open suspicious PDF document in another VM or 
different sandbox than a browser is contained in. Easy way to open 
document from copy-pasted URL will be an improvement over using browser 
or wget to download file just to see if it is interesting.
