JSON Stream Rust Tokenizer

A faster tokenizer for the `json-stream` Python library, this package ports `json-stream`'s internal tokenizer to Rust using PyO3, offering a significant parsing speedup (4-10x on CPython). As of `json-stream` version 2.0+, it is automatically detected and used by default, making explicit installation or usage generally unnecessary. It targets Python versions <3.15,>=3.8 and is actively maintained.
