How to filter TESS search results when many are available?

[gully]

We have a problem of abundance: often lightkurve search queries to MAST result in more than one result--- different data reduction authors, different sectors, and different exposure times (aka "cadence"). While it would be nice to handle all of these in a systematic way, it becomes a "big data" challenge and/or heterogeneous data problem.

I propose we solve this problem in two steps.
For now: simply pick whatever lightcurve comes first in the search result: lc = sr[0] This choice will help use move forward with building our analysis tools.

But eventually, I think we should adopt the ELEANOR-LITE standard (#11). These are not available yet (see the referenced issue). But when they are we can simply flip the switch to exclusively use those.
