Feature Request: Simple Way to Ignore Resources

Hi, I'd like to request a feature for a simple way of ignoring resource such that they don't end up in the diagram. Something like `Annotations.of(resource).addInfo("cdk-dia:ignore")` could maybe be used? See annotations docs [here](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.Annotations.html).
