Add a timeOffset in alternateEnclosure for better sync of transcripts

[Kolomona]

Add an attribute to alternateEnclosure of timeOffset (or similar)
When present offset the times used for time sensitive metadata such as transcripts, chapters, valueTimeSplits, etc.

My use case:
Jimmy V has a song called "Water is Sound". The song also a music video.

The music video has a 10ish second intro making the transcripts (lyrics) out of sync with the audio

I would like to be able to say to the app. "Hey the video is out of sync by 10 seconds from the regular enclosure so apply the offset to the lyrics as well as chapters."

The number should be a signed float with the "+" optional for positive numbers.

<podcast:alternateEnclosure type="video/mp4" length="48611412" bitrate="1561599" height="720" timeOffset="10.74">
  <podcast:source uri="https://music.jimmyv4v.com/bands/jimmy-v/jimmy-v-collection/water_is_sound/Water_is_Sound-Jimmy_V.mp4"/>
</podcast:alternateEnclosure>

Does this sound like a worthwhile thing to explore?
