Create granule geometry handler that creates a rectangular boundary

[eigenbeam]

As an operator,
When I want to ingest data where the data is (point, point collection, connected points, ...),
I can run MetGenC and it will generate UMM-G with a rectangular polygon boundary in EPSG:4326
...
I can specify a buffer size around the data
There is a default value for this parameter

What specific input geometry needs to be handled?
Does this need to handle more than lat/lon?

[lisakaser]

No buffer needed.

Input decision if 'point' or 'rectangle' should come from CMR read <- that story needs to be created. (Use CMR information)

A rectangular boundary only requires the upper left point and the lower right point of the bounding rectangle. Example from the NSIDC UMM-G guidelines:

"SpatialExtent": {
    "HorizontalSpatialDomain": {
      "Geometry": {
        "BoundingRectangles": [{
          "WestBoundingCoordinate": -180,
          "NorthBoundingCoordinate": 85.04450225830078,
          "EastBoundingCoordinate": 180,
          "SouthBoundingCoordinate": -85.04450225830078
        }],
      }
    }
  },
