2.1.0

EasyAR SDK 2.1.0 has a few new features and some stability improvements. Major highlights are,

1. New language support.

   EasyAR now support Swift on iOS and Kotlin on Android. We have also included new samples to show how to use Swift and Kotlin with EasyAR SDK.

2. Android arm64 support.

   From EasyAR SDK 2.1, arm64-v8a binaries for Android are included in the SDK package.

3. Bug fixes and stability improvements.

   We have fixed a few bugs introduced in EasyAR SDK 2.0, including jni local reference table overflow when calling ImageTarget.setupAll and video playback fail on iOS 11. We have also corrected camera image color output on screen which was a long existing bug.
