Add Python wrappers or create interoperability to call the classes/methods using Python

Data engineers quite heavily rely on Python for creating data pipelines. Its important to support the ability to call the Java objects using Python (through Py4J or similar tools/libraries). Right now, users can only use JVM languages out of the box if they were to use OneTable directly i.e. as shown in docker demo.

Start by reviewing the OneTable Docker demo and the Java classes and methods it exposes. Investigate Py4J or a comparable interoperability approach, then define the Python entry points and usage expected for calling OneTable from data pipelines. Done means Python users can invoke the relevant Java functionality through a documented, tested interface.
