Write a parser from our Clowder API to the required CSV fields.

Information:

• "mapping_drew" sheet
• "czo-datasets-metadata-2019-02-13" sheet
• Only the items set as “Map”
• We do not have CZO-ID
• Column W should be the raw variable names in the API (when downloaded)
• Remove columns not needed from latest data dump
• Requesting missing fields from IMLCZO researchers (may be a separate task)
