New feature

NativeLibsLocator#SetNativeLibraryPath(string) has been added.
This method makes AnimatedImage to reference libwebp libraries placed in your own location.
When using this method, AnimatedImage.Native is no longer required.

// using AnimatedImage;

var asmdir = Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly());
NativeLibsLocator.SetNativeLibraryPath(Path.Combine(asmdir, "Libs"));

To use WebP, AnimatedImage.Native library is required.

This package contains native libraries for the following platforms.

The original library drew and retained all frames when the image was loaded.
This library draw a frame for each time.
As a result, freezing during image loading is eliminated and memory usage is reduced.
