Command-line Interface

[moeyensj]

THOR needs a command-line interface that exposes more of its key functions.
Something like python runTHOR.py --task=link --inputs_dir={directory} as suggested by @spenczar .

Where task should probably be some of the following:

• link (run the full pipeline)
• propagate (propagate orbits to a desired time)
• ephemeris (generate ephemerides for an observer)
• iod
• od
• attribution
• test_orbits (find/create test orbits)

Additionally, the runTHOR.py script should be added as an entry point to the package. Example: https://github.com/B612-Asteroid-Institute/thorctl/blob/main/setup.cfg#L50
