Description

ARROW-10438 made is so that a "null" in a partition column will be mapped to a special directory with hive partitioning.  By default this is _HIVE_DEFAULT_PARTITION_ but it is configurable by other hive manipulation tools (e.g. spark) and so needs to be configurable in Arrow as well.  The `null_fallback` option is a string that can be passed to HivePartitioning::HivePartitioning and HivePartitioning::MakeFactory

This option should be exposed in R.
