Made some updates to https://github.com/ninarao/webvtt_metadata:
- Can now embed #FADGI #metadata in #WebVTT files using a csv, header data from an associated parent file, and/or an optional default metadata set
- Local usage elements can be added to the csv as needed
- Can create/update FADGI header for WebVTT files that have been human-reviewed
Feedback welcome! I've tested for various scenarios but there are many nested conditionals so I may have missed something.
