Technical Metadata Extraction for Visual and Temporal Retrievables

[ppanopticon]

Task Description

For 2D visual and temporal retrievables (e.g., images, video and audio frames), we need mechanisms to extract, store and retrieve technical metadata per retrievable.

• [x] Fundamentally, metadata of a certain type (e.g., temporal) should be implemented as a descriptor of type struct
• [x] Implement and integrate temporal metadata extraction and retrieval for video and audio (milliseconds, frame number)
• [x] Implement and integrate spatial metadata extraction and retrieval for video and images (width, height)

This has been done with TemporalMetadata and VideoSourceMetadata. If additional features are needed, open new ticket.
