Write a function that takes two equal-length buffers and produces their XOR combination.

If your function works properly, then when you feed it the string:

1c0111001f010100061a024b53535009181c

… after hex decoding, and when XOR’d against:

686974207468652062756c6c277320657965

… should produce:

746865206b696420646f6e277420706c6179
