Provide a data helper construct to synthetize data from S3 datasets

Dev/test environment can work on synthetic data extracted from production data. Synthetic data will allow to extract fake data with the same pattern as the production data.
We can use something like this tool https://github.com/awslabs/synthtable

Start by reviewing the repository structure and the existing data-solution entry points for how S3 datasets are accessed. Compare the requested helper with the linked awslabs/synthtable project, then define the supported input, generated output, and validation needed for synthetic data before implementation.
