Report to compare egress size from API vs full granule

[frankinspace]

As we move into production and start tracking usage metrics we should be able to quantify the amount of data being egressed from this API vs. if this API did not exist and the requests would have instead been required to download the entire shapefile to do the analysis.

If hydrocron did not exist, each request would need to be downloading multiple granlues from the shapefile swot collection. We should be able to build a dashboard or report which shows the 'theoretical' egress that would be required by users to build the same time series they can get directly from the API. We can then show a comparison of the size of the data egressed from the API.
