Automatically insert edits where different voices are identified in transcripts

After analysing sync in the transcribe function different speakers are identified. Add the option to automate adding cuts as speakers change and colour label different speakers. Then the option to remove a speaker (e.g. interviewer) and close gaps. Or separate the speakers if there are multiple talking heads, and then combine the same individuals as continuous sync.

This has the potential to save a lot of time pre-editing interviews.
