CityHash and FarmHash Python Bindings

CityHash is a family of fast non-cryptographic hash functions for strings, originally developed by Google. FarmHash is a successor designed for improved performance and collision resistance on modern CPUs. This library, `python-cityhash`, provides Python bindings for both CityHash and FarmHash, enabling high-performance hashing in Python applications. It is currently at version 0.4.10 and receives updates for Python version compatibility and Cython build fixes.
