/**
* Blake1 legacy hash function, one of SHA3 proposals.
* Rarely used. Check out blake2 or blake3 instead.
* https://www.aumasson.jp/blake/blake.pdf
*
* In the best case, there are 0 allocations.
*
* Differences from blake2:
*
* - BE instead of LE
* - Paddings, similar to MD5, RIPEMD, SHA1, SHA2, but:
* - length flag is located before actual length
* - padding block is compressed differently (no lengths)
* Instead of msg[sigma[k]], we have `msg[sigma[k]] ^ constants[sigma[k-1]]`
* (-1 for g1, g2 without -1)
* - Salt is XOR-ed into constants instead of state
* - Salt is XOR-ed with output in `compress`
* - Additional rows (+64 bytes) in SIGMA for new rounds
* - Different round count:
* - 14 / 10 rounds in blake256 / blake2s
* - 16 / 12 rounds in blake512 / blake2b
* - blake512: G1b: rotr 24 -> 25, G2b: rotr 63 -> 11
