Major Release: Native Rust Extension for 29x Faster Performance

This release introduces an optional native Rust extension built with PyO3 that provides approximately 29x faster JSON to XML conversion compared to pure Python.

New Features:

• feat: add optional Rust extension (json2xml-rs) for ~29x faster performance
• feat: add dicttoxml_fast module with automatic backend selection
• feat: seamless fallback to pure Python when Rust extension is not installed
• feat: pre-built wheels for Linux (x86_64, aarch64), macOS (Intel, Apple Silicon), Windows

Performance Improvements:

• Small JSON (47 bytes): 33x faster
• Medium JSON (3.2KB): 28x faster
• Large JSON (32KB): 30x faster
• Very Large JSON (323KB): 29x faster

New Files:

• rust/ - PyO3 Rust extension source code
• json2xml/dicttoxml_fast.py - Auto-selecting wrapper module
• tests/test_rust_dicttoxml.py - 65 comprehensive tests for Rust extension
• benchmark_rust.py - Performance comparison script
• .github/workflows/build-rust-wheels.yml - CI for building wheels
• .github/workflows/rust-ci.yml - CI for Rust code quality

Installation:

• Pure Python: pip install json2xml
• With Rust acceleration: pip install json2xml-rs (then import from dicttoxml_fast)

Documentation:

• Updated README with Rust extension usage and benchmarks
• Updated CONTRIBUTING with Rust development guide
