Screen capturing to detect animated (dynamic) dark patterns

[gunesacar]

We can use scrot to take screenshots automatically if Selenium somehow doesn't work:

Since we're set on using MutationSummary, I propose closing this.

In addition to using mutation summaries we started to capture the screen every second: https://github.com/gunesacar/OpenWPM/blob/mutation_summary/automation/Commands/utils/screen_capture.py
To minimize the storage overhead, we don't take a screenshot if the captured bitmap did not change.
