In `DataFramePartitioner.DataFrameFunctions.repartitionByRecordCount` use max instead of average to decide about partitoing

## Background
In `DataFramePartitioner.DataFrameFunctions.repartitionByRecordCount` the limit is compared against the average of records per partition. That can be under the limit while some partitions are still over the limit.

## Feature
Change the method to decide about portioning based on the `max` of record counts per partition if to do or not the repartitioing.
Or make this parametrized or a dedicated method.
