Calculates BLAKE3 hash string and returns the resulting set of bytes as FixedString.
This cryptographic hash-function is integrated into ClickHouse with BLAKE3 Rust library.
The function is rather fast and shows approximately two times faster performance compared to SHA-2, while generating hashes of the same length as SHA-256.
It returns a BLAKE3 hash as a byte array with type FixedString(32).

Function arrayFold(x1,...,xn,accum -> expression, array1,...,arrayn, init_accum) applies lambda function to a number of same sized array columns
and collects result in accumulator. Accumulator can be either constant or column.
