Add flags to cupid-run

[TeaganKing]

It would be great to include flags in cupid-run for running in serial. Default will probably be to use parallelized setup, but there should be an option to request to run in serial.

This will also require updating pyproject.toml and making run.py executable (add a main) instead of just a function. We should also use argparse to bring in additional command line arguments.

Potential arguments:

• serial vs parallel (default parallel?)
• what components to run (default all of them? Will require an update to config.yaml schema; see Change the cupid-run API? #63 for details)
• enable / disable time series generation
• verbose flag (maybe hide some warnings in Clean up or suppress DAG Render Warnings #76 under verbose?)
