Bigquery standard sql supports a json column type [link](https://cloud.google.com/bigquery/docs/reference/standard-sql/json_functions) it is not supported as a dialect type in this package [link](https://github.com/googleapis/python-bigquery-sqlalchemy/blob/main/sqlalchemy_bigquery/_types.py ) I'm sure many users will have a need for a nested column with no predefined schema, struct doesn't cover flexible nested records
