Interfaces are not importable.

For example:

(cdk/import [[IPrincipal] :from "@aws-cdk/aws-iam"])

The library throws the following exception:

1. Caused by java.lang.IllegalArgumentException
   No matching clause: interface

This also happens with some structs that are secretly interfaces, like https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-cloudfront.Behavior.html.
