refactor: Move cdf test expected results into tar

[OussamaSaoudi-db]

The cdf integration tests currently store the test data in compressed files (ex: cdf-table.tar.zstd). The expected output is a part of the test code in cdf.rs. Change the tests so that the expected results is in a parquet table that is also a part of the compressed file. This approach is similar to what we do in the dat tests.
