> When using `SqlImplementor.SimpleContext#toSql` with BigQuerySqlDialect on Rel nodes containing `CAST` need to convert Calcite SqlTypeName to BigQuery supported types ([https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types]).
> I believe this can be accomplished by Overriding BigQuerySqlDialect#getCastSpec method.
> Example: VARCHAR should become a STRING, BOOLEAN - BOOL, and so on.
