Desktopography extractor

[Jackymancs4]

Hello @mikf
recently I stumbled upon this site: https://desktopography.net/ which host a variety of high quality wallpaper in different resolutions.

So I created an extractor for it.

It supports

• the main site e.g. https://desktopography.net/
• a single yearly collection e.g. https://desktopography.net/exhibition-2020/
• a single entry (all the available sizes) e.g. https://desktopography.net/portfolios/new-era/

All files are saved as name_resolution.ext

I hope this is inline with the scope of the project.
If yes, upon review I expect the code to need to be cleaned up a bit.

Also, I'd appreciate some hints about what to do about the tests.

Thank you.

@Jackymancs4 Thank you very much.

I apologize for taking so long to merge this and to reply and get back to you. I didn't want to review and ask for changes and more work from your side after 1½ months, so I've simplified your code a bit myself, Mainly deleting unnecessary/commented lines and replacing your while loops with text.extract_iter().
