Work to address #5. This PR adds dra, ddec, and distance.

@spenczar Could you take a look at the changes to the obs.matches function and let me know your thoughts? There are two other commits in this PR, one that fixes a timedelta bug and another that disables the linear propagator. Disabling the linear propagator is a temporary change while we push forward on getting some of the candidates longer arcs of observation. Falling back to 2-body as our "approximate" propagation has made it so this code agrees 1-1 with the observations from brute-force attribution.

@spenczar I think this is ready for another look.
