Summary

NIFI-15057 - Add Record Path like helper methods for Record Transform Python processors

As a follow-up of NIFI-13672, I wanted to put together a processor that transforms records using a reader and writer and realised that we don't have an easy way to go through the dict representing the NiFi Record... So I'm adding helper methods that are a lightweight implementation of NiFi Record Path in order to make it easier to manipulate records using Python processors.

I didn't directly use the NiFi Record Path dependency as this would require a lot of back and forth between Java and Python in terms of mapping between the Java objects for using NiFi Record Path and we have on the Python side.

While not offering as rich features as the NiFi Record Path implementation, this provides a good start for basic scanning of the records which should cover most of the use cases.
