Farmer Importing - KML to JSON

We need a script to convert the KML to JSON and then send the data to the server's `add-farmer` endpoint.

Viewing a KML polygon:

Rough Steps:
1. Convert the Excel to csv (if it isn't already)
2. Map the csv farmer fields to the farmer object
3. Find that farmer's KML data
4. Use a library to convert the KML into geoJSON
5. send the farmer data and geoJSON to the `add-farmer` endpoint to convert it.
6. If we need to we can wrap the geojson with the field data.
