Wishlist: Adding all SHA3 candidates in SPHLib

[DonaldTsang]

1. 224, 256, 384 and 512 bit hash for each of these algorithms
2. Allow stripped variable outputs (like SHA512-256 or SHA512-384) Note: All SHA2 candidates uses the same basic input-output formats.

For libtomcrypt, it follows the format md5_init(&md); md5_process(&md, in, in_len); md5_done(&md, out); While for SPHLib, sph_md5_init(&md); sph_md5(&md, in, in_len); sph_md5_done(&md, out); So the syntax is nearly identical. Also, for SPHLib, hashes are md5.c headers are sph_md5.h tests are test_md5.c

Short notes regarding Key Derivation Functions

• "Old KDF strength" SCrypt > BCrypt > PBKDF2
• Finalist library https://github.com/mbroz/PHCtest
• Original competition Repo https://github.com/bsdphk/PHC

Winner and special recognition KDFs

• [ ] Argon2 (the winner, allows tweaking with hashes)
• [ ] Catena (allows tweaking with hashes)
• [ ] Makwa (allows tweaking with hashes)
• [ ] Lyra2 (allows tweaking with sponge functions)
• [ ] Yescrypt (based on Scrypt, needs Salsa20 and a hash function)

Finalists

• [ ] BATTCrypt (based on BCrypt, needs Blowfish and a hash function)
• [ ] Pufferfish (based on BCrypt, needs Blowfish, takes no hash function)
• [ ] Parallel (allows tweaking with hashes)
• [ ] Pomelo (does not allow tweaking with hashes)
