Problem

I got the unexpected animation after UX designer accelerating the original animation which has expected behavior, , It seems that I can get the correct animation with mainThread RenderingEngine only, renderingEngineOption.automatic doesn't work either. Old versions of Lottie-ios use mainThread RenderingEngine to create LottieAnimationView by default, but newer versions changed to coreAnimation. It seems that the coreAnimation RenderEngine with better performance but does't support my accelerated animation.

Please check the problem the fix it in future release
Thanks
