Add a Data Type?

[theory]

I would be interesting to add a jsonshcema data type that's effectively a serialized representation of a Schemas struct. Would also need to either store the $id of the base schema, or else some sort of mapping of $ids to the SchemaIndexs used by boon to identify the schemas within the compiled schemas object.

Then would need alternate sigatures for jsonschema_validates() to take a jsonschema type.

I don't know how possible this is. pgrx provides the #[derive(PostgresType)] macro to automatically serialize a struct as serde_cbor, so if the Schemas type can be serialized as CBOR it should be pretty straightforward.
