Buffered speaker diarization
**Is your feature request related to a problem? Please describe.**

For speaker diarization tasks tutorials and examples currently only offer scripts for offline diarization. I successfully got those running in combination with custom ASR models for Slovenian language. For ASR tasks the repository also contains scripts for buffered (streamed/live) inference, would such inference be possible for diarization?

**Describe the solution you'd like**

A tutorial or example on how to do buffered speaker diarization (if that is possible in the current framework). 

**Describe alternatives you've considered**

Some guidance about how I can implement this myself.
