[Request] Add national broadcast information to schedule data

[WardBrian]

It's possible to get information about where a game is being broadcast from the schedule endpoint:

https://statsapi.mlb.com/api/v1/schedule?sportId=1&date=2022-04-10&hydrate=broadcasts

Especially with all the new services, it would be great to include national broadcasts in the schedule() method's return data. I don't think non-national would be that valuable, since it will usually be the same network
