Use puppeteer in nodejs using webcodec to convert lottie file to mp4 video

No need to take screenshot of each frame (it takes much time）

Its workflow basiclly looks like this:

load in puppeteer lottie-web
encode each frame by webcodec API : VideoEncoder and VideoFrame
frames -> buffer -> blob -> file
send back to nodejs
use ffmpeg to generate video

I write a demo here https://github.com/Dramalf/puppeteer-webcodec-lottie/tree/master

I think it can be merged into this project
