Support for multiple formats of response data

[avanavana]

Currently all data from Airtable are sent to the user as JSON, formatted using names, format, and structure designed for Zotero, since originally the purpose of this proxy server was to download and sync the Airtable data with Zotero alone.

This format is far less useful to others, so I would like to create a format query parameter that uses a different default JSON structure, something closer to the data in Airtable itself, something more like what the future ESOVDB front-end website will use, and provide a few other formats.

Formats

• Default (Airtable JSON)
• Basic (simplified)
• YouTube (id, recordId, esovdbId, zoteroKey, added)
• Zotero (what I already have)
• GeoJSON (should filter any records lacking geospatial data)
• CSV
