There appear to be some fatal errors in the test scripts.

1. On the second test, expected output is the same as input. But this is after (apparently) applying the blur transformation.
2. Final test of codewars().rgb is throwing stdout error on both "Run Tests" and "Submit"

Apologies if I'm missing something!

EDIT: Looks like I misunderstood which pixels are used to compute the transformation (ie only reds affect other reds). Strongly suggest to clarify this in the description, thanks!
