Oniguruma CFFI

Onigurumacffi provides Python cffi bindings for the Oniguruma regex engine. Currently at version 1.5.0, it wraps the Oniguruma C library, offering a performant, multibyte-aware regex engine that operates primarily on bytes, distinct from Python's built-in `re` module. The library bundles the Oniguruma C source, simplifying installation, and requires Python 3.10 or newer. Releases are infrequent, tied to updates in the underlying Oniguruma library or CFFI.
