Added a reference implementation of the SipHash128 hashing function to ClickHouse.
Why it matters
This feature introduces SipHash128, a widely-used cryptographic hash function, to provide users with a secure, efficient hashing option. It aims to enhance data integrity and performance in hashing operations within ClickHouse.How to use it
Users can utilize the new SipHash128 function in their queries once it is available in ClickHouse. Typically, this involves calling the function directly in SQL statements to compute 128-bit hash values for given inputs.
