cat gzipped JSON files copied from SFM for full datasets

[lwrubel]

As mentioned in #140, copy JSON files (rather than loading and then extracting) for placement in full datasets directory. To reduce the number of files, consider concatenating files by day.

Naming convention for SFM data files starts with harvestid-datestamp.

Example SFM filenames:
