Add option to convert iFrames to images

[alexanderadam]

This one is probably a complicated one and should only be done if there's nothing else to do. 😉

See this post for example.

There's a GitHub code snipped embedded on the bottom.
If you want to archive the medium post with medup and the gist will be deleted, it will be gone forever.

So I guess it would be a good possibility to make a screenshot of the website in the frame, put it into the markdown and link the image to the original frame.
This way all information should stay archived.

There two possibilities to make a screenshot out of a page:

1. Using a free API (users should provide their own API data obviously)
2. Make a screenshot on your own. There are various Docker images with Chrome or Firefox integrated and there are Shards like marionette, selenium-webdriver or stoertebeker that allow controlling a browser from Crystal (see also this issue).

This has to be an option of course. Because making screenshots will obviously slow down the process.
