Allow pdf generation to work when HTTP authentication is enabled for a domain/server

I have done a search through the issue queue, and couldn't find a similar posting to this, so my apologies if this is a duplicate.

When building sites for clients, we commonly use HTTP authorization on non-production sites (such as development, or staging sites) as a means of ensuring that these sites dont get picked up search engines, or that they aren't accessible to anyone other than ourselves and the client.

Currently with Entity Print 8.x-1.x, when testing on such a site the PDF generation fails with 401 Authorization Required error. This means any HTTP authorization has to be turned off to allow the PDF generation to be tested.

Would it be possible to add a 'develop' mode where by any auth details could be added to the settings page for the module?

This way, when PDF generation is tested on a site/server utilising HTTP authorization, these details could be taken into account to avoid the 401 error.
