Spsc-ring-threadsafe Python C ext. 100x faster as multiprocessing.Queue

A Python C extension implementing a single-producer single-consumer (SPSC) ring buffer designed for thread-safe inter-thread communication. It provides a faster alternative to Python's built-in multiprocessing.Queue for use cases where only one thread writes and one thread reads. The implementation leverages low-level C code to reduce overhead compared to standard Python queue abstractions.
