Version 0.2.2

- 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.

main.rs:

extern crate jpeg_decoder as jpeg;

use std::fs::File;
use std::io::BufReader;

fn main() {
    let file = File::open("hello_world.jpg").expect("failed to open file");
    let mut decoder = jpeg::Decoder::new(BufReader::new(file));
    let pixels = decoder.decode().expect("failed to decode image");
    let metadata = decoder.info().unwrap();
}
