murmur3_x86_32
def murmur3_x86_32(data: Span[UInt8], seed: UInt32 = UInt32(0)) -> UInt32hashes.murmur3
MurmurHash3_x86_32, plus the Iceberg Appendix-B pre-hash wrappers.
Iceberg's bucket[N] partition transform is (hash(v) & Int32.MAX) % N
where hash is MurmurHash3 x86-32 with seed 0 over a type-specific byte
serialization (spec: https://iceberg.apache.org/spec/#appendix-b-32-bit-hash-requirements).
