Add mdbook-slide-evaluator (#2258)

I created a first implementation for the mdbook-slide-evaluator I
described in #2234.

One has to run a WebDriver compatible browser (e.g. selenium-chromium)
so the slides can be rendered. The browser can access the file either
via a file:// or http:// uri.

The tool grabs the configurable element from that page and evaluates the
size of this element. Output can be stored in a csv file or at stdout
and looks like this at the moment:
```
