Batch-mode CLI interface MVP (for testing and validation).

[DylanLukes]

Requires for MVP...

• [x] #5
• [x] ~#9~
• [ ] #7

Removing dependency on #9 as it can be skipped for MVP for testing and validation.

CLI MVP parts:

• [x] Input data handling (read CSV/Parquet/Feather)
• [x] Global config object (singleton). Smelly but easier to iterate on.
• [ ] Store input data in store ($CWD/.renkon directory by default, change later as this pollutes, or use flag?)
• [ ] Initialize trivial task graph (no edges)
• TBD

Note: In the interest of simplicity, it might be easiest to have server mode be the "one true mode", and set up batch mode to simply spin up a server, feed it, and then spin it down.

This would also enable, later on, something like renkon --attach <existing PID or socket>, to directly call Renkon running under Jupyter from a terminal.

Depends on #13 and #14.
