// keyScheduleRound contains the magic values for a round of the key schedule.
// The keyScheduleA deals with the lines like:
// z0z1z2z3 = x0x1x2x3 ^ S5[xD] ^ S6[xF] ^ S7[xC] ^ S8[xE] ^ S7[x8]
// Conceptually, both x and z are in the same array, x first. The first
// element describes which word of this array gets written to and the
// second, which word gets read. So, for the line above, it's "4, 0", because
// it's writing to the first word of z, which, being after x, is word 4, and
// reading from the first word of x: word 0.
//
// Next are the indexes into the S-boxes. Now the array is treated as bytes. So
// "xD" is 0xd. The first byte of z is written as "16 + 0", just to be clear
// that it's z that we're indexing.
//
// keyScheduleB deals with lines like:
// K1 = S5[z8] ^ S6[z9] ^ S7[z7] ^ S8[z6] ^ S5[z2]
// "K1" is ignored because key words are always written in order. So the five
// elements are the S-box indexes. They use the same form as in keyScheduleA,
// above.
