How to use this library :

To load animated png to an imageview : 
```kotlin

val imageUrl = "https://upload.wikimedia.org/wikipedia/commons/1/14/Animated_PNG_example_bouncing_beach_ball.png" // image url could be an url, or a file path. You could also load byteArray and file

val animator = ApngAnimator(imageView)
animator.load(imageUrl)

animator.play()
```

To create animated png :

```kotlin

val apng = Apng()

val file1 = File("image path 1")
val file2 = File("image path 2")

apng.addFrames(BitmapFactory.decodeByteArray(file1.readBytes(), 0, file1.readBytes().size))
apng.addFrames(BitmapFactory.decodeByteArray(file2.readBytes(), 0, file2.readBytes().size))

val apngByteArray = apng.generateAPNGByteArray()
File("output file path").writeBytes(apngByteArray)
```
