GEDZip will require the following

• A JavaScript library for reading and writing zip files. One person recommended https://stuk.github.io/jszip/ bit I've not used it or any other JavaScript zip tool before so I'd want to explore a bit before settling
• Adding in file path detection and validation. Unfortunately, at the time of writing that is not programmatically checkable (FILE has a <string> payload, not a <filepath> payload)
• Methods for handling adding, changing, and removing linked files
