func SelectNextProducers

func ShuffleList 

func ShuffleList(input []uint64, seed [32]byte) ([]uint64, error)

ShuffleList returns list of shuffled indexes in a pseudorandom permutation `p` of `0...list_size - 1` with “seed“ as entropy. We utilize 'swap or not' shuffling in this implementation; we are allocating the memory with the seed that stays constant between iterations instead of reallocating it each iteration as in the spec. This implementation is based on the original implementation from protolambda, https://github.com/protolambda/eth2-shuffle 

improvements:
 - seed is always the first 32 bytes of the hash input, we just copy it into the buffer one time.
 - add round byte to seed and hash that part of the buffer.
 - split up the for-loop in two:
  1. Handle the part from 0 (incl) to pivot (incl). This is mirrored around (pivot / 2).
  2. Handle the part from pivot (excl) to N (excl). This is mirrored around ((pivot / 2) + (size/2)).
 - hash source every 256 iterations.
 - change byteV every 8 iterations.
 - we start at the edges, and work back to the mirror point.
   this makes us process each pear exactly once (instead of unnecessarily twice, like in the spec).
