Your mission is to calculate the area covered by a union of rectangles. The rectangles can have a non-empty intersection, which means that a simple sum of given rectangle areas doesn't work. Every rectangle is represented as 4 integers. The first two integers are the coordinates of a left-top corner, and the next two - of a bottom right corner.
Input: Iterable with tuples.
rectangles_union([ (6, 3, 8, 10), (4, 8, 11, 10), (16, 8, 19, 11) ]) == 33
