 Review comment:
   I was inspired by other existing places such as [this](https://github.com/apache/incubator-iceberg/blob/master/spark/src/main/java/org/apache/iceberg/spark/PruneColumnsWithReordering.java#L107). It was a bit unclear what `current` means until I saw that `current = requestedType` initially. Since this class is about pruning `requested` made sense to me.
   
   If we keep `requested` in the name, conditions are self-descriptive `requestedDecimal.scale() == decimal.scale()`.
