`ScalarValue::to_array_of_size` panics computing statistics for nested parquet file

[tustvold]

Describe the bug

let ctx = SessionContext::new();

let mut options = ParquetReadOptions::default()
    .parquet_pruning(true)
    .to_listing_options(2);

// Disable stats collection
options.collect_stat = true;

ctx.register_listing_table("patient", "/home/raphael/Downloads/part-00000-f6337bce-7fcd-4021-9f9d-040413ea83f8-c000.snappy.parquet", options, None).await.unwrap();

let df = ctx.sql("SELECT patient.meta FROM patient LIMIT 10").await.unwrap();
df.show().await.unwrap();

Where part-00000-f6337bce-7fcd-4021-9f9d-040413ea83f8-c000.snappy.parquet is the parquet file provided by @kesavkolla in #2439

Setting options.collect_stat = false eliminates the panic

Expected behavior

The above should not panic

Additional context

Follow on for #2453 which is fixed by #2631

[HuSen8891]

I think the merge request #2671 already fix this.

Huzzah, can confirm 🎉
