Captions list to be editable

[dylman123]

Need to create the capability to:

1. Edit: timing values, caption text (with support for multiline text), speaker name (autofill & dropdown menu).
2. Add: new captions into the list (with timing & speaker initialised with default dynamic values).
3. Delete: existing captions from the list
4. Handle simultaneous captions (when speakers speak at the same time) - unlikely to be generated by any transcription service with single channel audio. But this may occur with: a) Manual edits and b) Multiple channel audio
5. Set: a maximum caption length (maybe a column width slider?). Captions that exceed this length will be automatically split.
6. Split: one caption into two
7. Merge: multiple captions into one (must enforce a reasonable max word limit)
