adam_core interfaces

[ntellis]

This PR adds:

• to/from adam_core functions for precovery.Orbit
• quivr tables that mimic PrecoveryCandidate and FrameCandidate, with constructors from a list of either. This table is flat, but includes convenience methods to construct the adam_core classes (ex Residuals, Ephemeris for the predicted positions)

As written, precover() and precover_many() both accept either a precovery.Orbit or an adam_core Orbits. They output the old PrecoveryCandidate and FrameCandidate, though - this way they don't break anything existing in cutouts or adam_etl.

To get the more useful PrecoveryCandidateQv, the constructor is:

PrecoveryCandidatesQv.from_precovery_candidates([cand1, cand2, cand3])

I think it will be easiest to just call this after running precovery normally, where desired.

I also borrowed drop_duplicates from thor. This could probably be promoted to quivr

Dependencies are borked here, may need to update to using pyproject.toml, as well as change some things with pyoorb in order to get this working.

Adopt dockerfile structure for adam_core/adam_etl for installing pyoorb, switch to pyproject.toml due to recent setuptools main version.
