Expand Haraka https://github.com/kste/haraka by adding a Haraka-1024 function, which maps 1024 to 256 bits. The sponge version of Haraka (Haraka_S) is based on the implementation from SPHINCS+ (available here https://sphincs.org/software.html). Our construction match the security level of SHAKE256 (https://keccak.team/specifications.html#FIPS_202).
