✨ use ffmpeg to encode raw pcm (#69)

* ✨ use ffmpeg to encode raw pcm

* 🚨 lint

* 💚 install ffmpeg in ci

* 👷 update ci setup-ffmpeg action

* 👷 nvm, install ffmpeg myself

* 🐛 use old way to get supported formats

since the new `avcodec_get_supported_config` is too new

* 💡 comment out the new function
