The docs say that [ProducerScore has a required field `encodingIdx`](https://mediasoup.org/documentation/v3/mediasoup/api/#ProducerScore), but the [type in Producer.ts does not contain the field](https://github.com/versatica/mediasoup/blob/d3d369ecf3e255a6da04cc6d35098a3fd6bd6f22/src/Producer.ts#L72-L88). Should the docs or the type be updated?
