Cython Hash Table for Pre-Hashed Keys

preshed is a high-performance Cython library for Python that provides efficient hash table data structures. It's designed for use cases where keys are already pre-hashed, offering `PreshMap` for key-value storage, `PreshCounter` for frequency counting, and `BloomFilter` for probabilistic set membership testing. Maintained by Explosion (the creators of spaCy), it sees regular updates primarily for Python version compatibility and performance enhancements, with occasional major releases introducing significant architectural changes.
