I just ran the new integration test and it fails (as expected) with this PR as we have enabled some new features.

cargo test --all-features variant_integration

Fails like this:

failures:

---- test_variant_integration_case_31 stdout ----
VariantTestCase {
    case_number: 31,
    test: Some(
        "testShreddedVariantPrimitives",
    ),
    parquet_file: Some(
        "case-031.parquet",
    ),
    variant_file: Some(
        "case-031_row-0.variant.bin",
    ),
    variant_files: None,
    error_message: None,
    variant_description: None,
}
note: test did not panic as expected at parquet/tests/variant_integration.rs:58:16
---- test_variant_integration_case_30 stdout ----
VariantTestCase {
    case_number: 30,
    test: Some(
        "testShreddedVariantPrimitives",
    ),
    parquet_file: Some(
        "case-030.parquet",
    ),
    variant_file: Some(
        "case-030_row-0.variant.bin",
    ),
    variant_files: None,
    error_message: None,
    variant_description: None,
}
note: test did not panic as expected at parquet/tests/variant_integration.rs:58:16

failures:
    test_variant_integration_case_30
    test_variant_integration_case_31

I just pushed a commit to fix the CI to run the tests, and will push another one to fix the tests
