Description

The idea is to do a proof of concept before developing the UDF API or required kernels as a PR. 

This PoC will be looking into a few ideas. 

• Using Project (ProjectNodeOptions) to execute a simple Python function which serves as a UDF
• Using Aggregate (AggregateNodeOptions) to execute a simple Python function which servers as a UDF
