 There are a few ways to provide an attachment serializer: directly implementing `IAttachmentSerializer`, implementing `INBTSerializable` and using the static `AttachmentSerializer.serializable()` method to create the builder, or providing a codec to the builder. (This latter option is not recommended for item stacks due to relatively slowness).
