FEP-ee3a: Exif metadata support

Hi everyone!

This discussion concerns a FEP that describes how platforms can add support for exchanging Exif metadata between each other. This metadata can be extracted from image and audio files and is typically added automatically by the devices that create those files (for example digital cameras).

Photographers very often share Exif data today, usually by including it manually in the status content (often as an emoji followed by a value). However, this process is entirely manual. Client applications, on the other hand, are able to read this metadata automatically and after explicit user confirmation (which is a critical step) store it in their databases and exchange it with other platforms.

For photography-oriented platforms, this enables additional functionality, such as filtering photos taken with a specific camera body, a particular lens, and similar criteria.
