Optimized SIMD routines for escaping JSON strings. The implementation is fromsonic-rs, we only take the string escaping part to avoid the abstraction overhead.

Numbers below come fromcargo bench runs on GitHub Actions hardware. Criterion reports are summarized to make it easier to spot relative performance. "vs fastest" shows how much slower each implementation is compared to the fastest entry in the table (1.00× means fastest).
