- Added and SSE3-specific SIMD intrinsic implementation for idct and color
  conversion. It will run if applicable targets are detect at _runtime_.
- The SIMD implementation is not bit-for-bit compatible with non-SIMD output.
  You can enable the `platform_independent` feature, to ensure that only
  bit-for-bit equivalent code runs and output is the same on all platforms.
- Improved performance some more by avoiding bounds checks with array types.
- Multithreading is now used more frequently, without the rayon target, except
  on an explicit list of unsupported platforms.
