[draft] Lisp code for collaboration

[bmcdonald3]

This is a draft implementation of the lisp code being opened for easy sharing. This branch has the ObjectPool optimization as a work in progress with values hardcoded for the my_axpy function and works for the stream benchmark, but will not work generally.

To run the benchmark on this branch:

1. Make with the ServerModules.cfg file included (this is the minimum build for the benchmark)
2. Start the Arkouda server
3. Run ./benchmarks/stream.py <hostname> <port> --size=100000 --lisp
   • small size since lisp code doesn't perform very well at the moment
   • --lisp flag runs the lisp benchmark

For a fully-functional branch that doesn't perform as well, see: https://github.com/bmcdonald3/arkouda/tree/lisp-code
