Select optimal Spongos PRP and hash function for embedded devices

Priortiy: (C)

Spongos transform (PRP) and hash function directly impact performance of message processing and hash-based crypto (WOTS, MSS). Current choice of Troika and Keccak-F[1600] may not be the best choice for binary or embedded devices.

Key results

1. • Consider sponge-based algorithms

     and hash-functions
     https://blake2.net/
     http://bench.cr.yp.to/primitives-hash.html
2. • Run benchmarks on different platforms (PC, raspberryPi, android, etc.); compare results against Troika and Keccak-F[1600] permutations
3. • Add implementations for PRP trait (https://github.com/iotaledger/streams/blob/master/iota-streams-core/src/sponge/prp/prp.rs#L12) and Hash trait (https://github.com/iotaledger/streams/blob/master/iota-streams-core/src/hash/mod.rs#L8)
