Transformers assume data column values are strings but they can be numerical (int) so convert it to string to avoid type errors.
Put the change in hyper transformer over the sdv repo because this allows us to maintain integrity of the input data and the created synthetic data (avoid type changing of columns). The changes are build for intermediate steps so it won't affect the data itself.
