Create csv to json uploader

[superjai]

Hey @robbiecarroll. Let's get started on thinking about Javascript figures in WordPress. First step in that journey? Getting the data files into WordPress. The data uploader will take the place of the following placeholder in the Figures form:

1. The data format of the incoming file should be csv with a header row.
2. In your process, you should convert the uploaded csv file to a json file.
3. That json file should be saved in the following location: wp-content/data/instance-slug/file-name.json
4. Delete the original uploaded csv file when the json file is in place.
