That way you can use other sources than the file system for loading pdfs.

Description of your pull request

I needed the ability to load pdfs from other sources than files, in my case e-mails.

Why should it be considered?

It's a small change and it adds a lot of useful functionality.

Hello @cguckes

Sorry that I didn't spot this before and thanks for your PR.

I've got a couple of pedantic suggestions, I hope you don't mind :)

• instead of doing this merge:
  
  can you ensure that there are only non-merge commits in there?
• if you can ensure that this commit's message: cguckes@5c968dd conforms to the git commit style guide: https://chris.beams.io/posts/git-commit/

If this is too much work/annoying, let me know, and I'll do it.

Thanks

@dotemacs, will do when I get the chance. Might be one or two days though...
