(#154) Filters for ListedImages

[llorllale]

This PR is for #154:

• Adds filtering capability for ListedImages according to the docs.

This PR took me way longer than it looks. The documentation referenced above is not entirely clear, and searches for some examples yield filters not included in the documentation(!) (1, 2).

I have not tested this solution against a live docker instance, and I'm not quite satisfied both with the efficiency of the unit test I wrote, nor with the elegance of both the implementation and test. ¯\_(ツ)_/¯ Maybe we can add a puzzle for that. Maybe we can also wait for #153 and make sure this actually works when we implement integration tests for that.

@amihaiemil I can't be REV :)

@llorllale well, looks ok. We'll see about integration testing, later. I boosted the original task 6x now, that is the maximum according to the Policy :D
