    NIFI-5533: Be more efficient with heap utilization
     - Updated FlowFile Repo / Write Ahead Log so that any update that writes more than 1 MB of data is written to a file inside the FlowFile Repo rather than being buffered in memory
     - Update SplitText so that it does not hold FlowFiles that are not the latest version in heap. Doing them from being garbage collected, so while the Process Session is holding the latest version of the FlowFile, SplitText is holding an older version, and this results in two copies of the same FlowFile object
