Add day 4
I really enjoyed day 4, I thought it was a particularly beautiful puzzle
where part 2 led on very nicely from part 1. Then again, I do always
tend to like these self-referential things
I started off putting all my integers to the minimum size, but in part 2
I gave up and just used usize, because I didn't really know how big the
numbers were likely to grow... this was fulled by me initially
misreading it as being based on the "score" not the "n" which would have
resulted in much larger numbers
Here's to hoping for an as-satisfying day 5!
