There were some improvements I forgot to make before merging #96.
I wanted to add a comment to evi_message.dart to clarify that the types are incomplete and where to find the docs if you need to access more properties.
I realized that I was actually only like 50% of the way through adding types, and there was still .rawJson being used in a bunch of places, so I finished that.
I needed to rename ChatMessage to ChatEntry because as I was adding more API types I wanted to avoid confusion with evi.ChatMessage.
