ChibiHash.V2

V2 implementation of ChibiHash

This is a 64-bit non-cryptographic hash function optimized for: - Fast performance on short strings - Good distribution of hash values - Simple implementation with no lookup tables

Version 2 improvements over V1, from the original C implementation:

• Faster performance on short strings (42 cycleshash vs 34 cycleshash)
• Improved seeding that affects all 256 bits of internal state
• Better mixing in bulk data processing
• Passes all 252 tests in smhasher3 (commit 34093a3), v1 failed 3.
