You need to create a Terraform module that can dynamically provision AWS S3 buckets and IAM roles

based on a list of JSON configurations. The module should take a list of JSON configurations as input

and be versatile enough to handle various S3 bucket and IAM role definitions. It should be able to

create multiple instances of each as specified in the input configuration. The JSON configurations

should specify the S3 bucket and IAM role names, along with any additional attributes you think

provide value (e.g., bucket policies, encryption, logs, etc).
