Support load dotlottie for setAnimation(InputStream) #2409

Currently it looks like only support json, can we add support for zip?

I'm using this as workaround for now:

val stream = FileInputStream(File(filepath))
val result = LottieCompositionFactory.fromZipStreamSync(ZipInputStream(stream), filepath.hashCode().toString())
val composition = result.value ?: throw IllegalStateException("Unable to parse ${filepath}")
view.setComposition(composition)

Also, change from fromZipStreamSync to fromZipStream can be complex, maybe make view.setCompositionTask public will be better.

Sorry, I don't understand the question. Can you attach a zip file that isn't working correctly?

I believe the request is to expose a setter on LottieAnimationView that works with zip/.lottie sources. The existing InputStream setter assumes that the stream is backed by json.

File is here: test.lottie.zip

After #1660 we can use .lottie files by check file extension to use zip input stream, but currently the LottieAnimationView.setAnimation(InputStream) cannot detect for that, it only expected the input is JSON. In my case I want to use local dotlottie files.

Do you think use API like PushBackInputStream to check bytes head is good idea, or just add a new API instead?
