Foolproof: Disable VAD if clip_timestamps is in use

@Purfview , could you provide an example of the strange behavior if using both vad_filter and clip_timestamp ?

clip_timestamps is like custom/manual VAD and it runs after Silero VAD code. Them both running at same time doesn't make sense.

For example, if you want to transcribe only the third minute of audio and set clip_timestamps="120,180", if vad_filter is enabled then audio for clip_timestamps can be different and the third minute wouldn't be at "120,180" anymore, transcription would happen at some unknown portion of audio.

Okay. But I think you should add a comment or logging for this update logic code: vad_filter will be ignored if clip_timestamp is used.
