WIP Parsing Facebook data export.md

1. Export data
2. Unzip
3. cd facebook-<username>
4. find . -type f -name '*.json' | xargs -n1 jq -c '. as $input | {} | setpath(input_filename / "/"; $input)'

=> This'll get you to a one-file-per-line stream of JSON objects formatted with the filepath (relative to the export root) as the nested JSON object path. So e.g. a file at ./ads/ad_interests.json containing JSON content:

{
  "topics": [
    "Facebook Messenger",
    "Instant messaging",
    "Reddit",
    "Social network"
  ]
}

Would end up like:

{".":{"ads":{"ads_interests.json":{"topics":["Facebook Messenger","Instant messaging","Reddit","Social network"]}}}}

Next step is to merge into a single JSON blob, and then use a JSON Schema generator tool to explore the structure and turn into a Singer tap.
