Neynar

Something that has often been requested is the ability to see which app a cast was created through.

From now on, all hydrated cast objects that Neynar APIs return will include info about the app that created the cast. We also added a new `app_fid` parameter to the `v2/farcaster/feed/user/casts` API so the returned list of casts can be filtered by app FID, e.g. specify 9152 to only get a user's casts that were created via @warpcast (see docs here: https://docs.neynar.com/reference/fetch-casts-for-user).

Are there any other APIs you would like to filter by app FID? 🪐

Great addition! How about enabling app FID filtering for the `v2/farcaster/following` API?
