Allow configuring `playbackContext` in `getInfo`

[mmjee]

Describe your suggestion

In the example of playing a video from YouTube using InnerTube and GoogleVideo, the streaming data needs to be fetched with { adPlaybackContext: { pyv: true } } apparently. I don't know the significance of this but it doesn't work without this.

However, if I wanted to use InnerTube's getInfo to get the streaming data alongside other metadata, it doesn't pass this and doesn't allow configuring it to pass this. I made it work by simply hard-coding it in my fork but I think there needs to be a way to configure the playbackContext.
