Example: add lottie implementation

[TheRogue76]

This is what it would look like if you wanted to make your own native component, for example Lottie.
Out of all the files here, i only modified the following myself:

1. native-views/NativeViews.podspec where i added the iOS dependency
2. native-views/android/build.gradle where i added the android dependency
3. native-views/android/src/main/java/com/margelo/nitro/nativeviews/HybridLottie.kt my Android implementation
4. native-views/android/src/main/java/com/margelo/nitro/nativeviews/NativeViewsPackage.kt me adding my view to the list of views RN knows about
5. native-views/ios/LottieView.swift my iOS implementation
6. native-views/nitro.json, native-views/src/Lottie.nitro.ts and native-views/src/index.tsx me declaring the new view
7. src/views/HomeScreen/HomeScreenContent.tsx me using the view

Everything else is codegen'd. I didn't have to wrangle anything to make this work
