Follows List about cips HOT 3 OPEN

@oed the schema for the follows list would likely just be an array of DIDs, but I could imagine that being useful for other documents as well. Should we create a new CIP for a DID Array Schema, similar to what we did for DocId Map and String Map?

Well this is an interesting find. My team and I actually discussed this a while ago. We came to the conclusion that, in addition to the follows list, there should be a following list. This would allow both the follower and the DID being followed to confirm if a relationship exists or not.

The problem with a "who is following me" list is that it's hard to update that list in a trustless way. When Alice decides to follow Bob, it's easy for Alice to update her own IDX to include a record that she is following Bob. She cannot, however, write to Bob's IDX to add herself as a follower as she won't have write access to the necessary streams that Bob owns.
