[Feature Request] LUFS Loudness Characteristics

[MironVeryanskiy]

This feature request is to enable LUFS (Loudness Units Relative to Full Scale) metrics into Friture. https://en.wikipedia.org/wiki/LUFS (also referred to as LKFS)

After recently learning that different web platforms will auto-normalize audio to their own pre-selected LUFS points, I am interested in sanity-checking for this behavior across my audio sources.

Uncertain about image attribution - multiple blogs reuse the same graphic when querying "lufs for streaming platforms 2024" in a search engine.
