bookDistribution message type.
I want to augment the book feature in SSB with a new message type called
bookDistribution that contains a reference — link or blob — to where the book is available. This could be used to distribute digital books inside SSB feeds (provided you have the right to do so) or link to where a reader can obtain them on the Web or some other protocol.
This message is an attempt to work with the community on this instead of simply shipping the feature without a healthy convo.
