Release v0.2.0

Artifact: com.camerakit:jpegkit:0.2.0

What's New

Adds a wrapper class so you can work with libjpeg-turbo running in the Android JNI, all from higher level java methods.
See turbojpeg.h in libjpeg-turbo's repository for official documentation. Our wrapper is mostly the same.

A view class for rendering a jpeg.
Uses a pixel allocation reference to the JNI layer created by the TurboJpeg wrapper.
Pixel RGB data always stays off JVM.
- Lower risk of memory issues.
Executes a memcpy directly to the window's low-level pixel buffer.

Render latency comparison:

This class receives a jpeg byte[] in it's constructor, which is subsequently marshalled to the JNI layer.
The jpeg's header data is decompressed immediately in the constructor, so metadata methods will work immediately with low overhead:
- getWidth()
- getHeight()
- getSubsampling()
Decode methods available:
- decode()
- decode(...)
  - int width
  - int height
  - int pitch
  - @PixelFormat int pixelFormat
  - @Flag int flags
- decodeToYuv()
- decodeToYuv(...)
  - @Flag int flags
- When unsure about a value in the parameterized versions of these methods, it's always safe and handled internally if you put 0
You must call release() when you are finished.

This class receives a jpeg byte[] in it's constructor, which is subsequently marshalled to the JNI layer.
Transformations available:
- flipHorizontal()
- flipVertical()
- rotate(...)
  - int degrees
- cropWithOffsets(...)
  - int leftOffset, int topOffset, int rightOffset, int bottomOffset
- cropWithRegion(...)
  - int x, int y, int width, int height
When finished, you can have the transformed jpeg data unmarshalled back to the android JVM with obtain().
You must call release() when you are finished.
