rails ActiveModel::Attributes support

[james-caresnap]

I have some rails models with custom Postgres jsonb attributes which are serialized/deserialized using the Attributes API. In other words, they are POROs with the following mixins:

• ActiveModel::Model
• ActiveModel::Attributes
• ActiveModel::Serialization

It looks like amazing_print just dumps these by calling inspect on them. What's the right way to add support to amazing print for these types? Add something to amazing_print/lib/amazing_print/ext/? Or modify the ActiveRecord extension? It looks like maybe you could just add another switch case here?

Hey @james-caresnap sorry for the super delayed response but this sounds like a great idea! Sounds like ActiveRecord extension should be fine for this. I welcome a pull request!
