Decimal Statistics emitted by parquet-cpp are broken

PARQUET-1655 min/max statistics for Decimal logical types that are encoded as byte arrays or fixed length byte arrays are potentially broken.  All reader implementations should ignore/clear them for parquet for files written with a version included "parquet-cpp"

This serves as a parent tracking issue. To fix various readers.

Non sono nominati file, test o punti di ingresso. Inizia individuando le implementazioni dei reader che gestiscono i Decimal logical types ed esamina PARQUET-1655; il lavoro è completato quando tutti i reader interessati ignorano o cancellano le statistiche min/max per i file scritti con parquet-cpp.
