v0.1.13

Changes

• turbojpeg enabled by default in published wheels (2-4× faster JPEG encode/decode vs pure-Rust fallback)
• Windows CI fixed: pin CMAKE_GENERATOR=Visual Studio 17 2022 to prevent cmake auto-selecting VS 2026 preview
• All turbojpeg code paths gated behind #[cfg(feature = "turbojpeg")] — pure-Rust fallback still works for source builds without cmake
