Allow point as granule spatial representation

[lisakaser]

Handle "Point" granule level spatial representation (info is in CMR)

Sample data set: needed (likely a CSV/ASCII)

points might need to be re projected if not in 4326

Open question: Clarify if Point is single location or could be file with multiple point locations (Amy)

Acceptance criteria:
UMM-G should show correct geometry with one point or array of points

@afitzgerrell the specific question here for you is if a file/granule has to match to one point or if there could be a file that has multiple point locations inside that all should be handed off to UMM-G.

Technically (from a CMR perspective) a granule is allowed to be represented by multiple point locations. Functionally, however, current-SIPSmetgen expects a point granule's spatial representation to comprise a single lon/lat coordinate pair, thus this is the immediate case that MetGenC should handle.
