AM Lottie Web

This is a modified version of Airbnb's lottie-web, made to adress the following issues:
- Safer and more efficient handling of After Effects expressions. This codebase does not rely on eval to execute expressions made with After Effects, making it safer and also slightly faster.
- Server Side Rendering in Node environments. All calls to browser or Web API are wrapped in environment checks.
- Better error handling. A big problem with the original codebase was that it would fail silently. This made development and user feedback difficult.

This package is primarily made to work with @aarsteinmedia/dotlottie-player, and @aarsteinmedia/dotlottie-react. Any use cases outside of that are incidental and due to inherited features of airbnb/lottie-web.
