A jpeg decoder with wings.

|x86| ✅ | Enables x86 specific instructions, specifically avx and sse for accelerated decoding.|
The decoder heavily relies on platform specific intrinsics, namely AVX2 and SSE to gain speed-ups in decoding,
but in debug build rust generally doesn't like platform specific intrinsics (try passing -O parameter to see optimized build) hence obviously speeds tank so bad during debug builds, and there is probably nothing
we can do about that.
The decoder is blazingly fast, especially on x86_64 with AVX2 enabled CPU's(most cpu's from 2013).
Even with CPU's that don't support these extensions, the code is carefully written to allow the auto-vectorizer to accelerate for whatever platforms in mind.
Furthermore, we take advantage of multi-core CPU's to accelerate post-processing of images to bring 1.5x performance edge over [libjpeg-turbo] and 2x over [image-rs/jpeg-decoder].
For more up-to-date benchmarks, see Benches.md.
Note, we do not try to recover corrupt JPEG's, your best bet is libjpeg-turbo for that, all errors are propagated up to the caller.
