What
This PR updates the datafusion table provider to use 14 target streams, as per the default in DataFusion. It hashes the partition ID modulo 14 when creating the streams. In the next version we will pass through the
target_partitionsfrom the session context, but we have a larger effort to move to multiple streams ongoing. We will include passing through the target partition size as part of that larger effort.
