// We want to calculate the sum (h) for a 64 byte message (m):
//
//   h = m[0:16]r⁴ + m[16:32]r³ + m[32:48]r² + m[48:64]r
//
// To do this we split the calculation into the even indices
// and odd indices of the message. These form our SIMD 'lanes':
//
//   h = m[ 0:16]r⁴ + m[32:48]r² +   <- lane 0
//       m[16:32]r³ + m[48:64]r      <- lane 1
//
// To calculate this iteratively we refactor so that both lanes
