RAI depends on multiple packages. Some of them should be optional

Describe the solution you'd like
Plan:

rai_asr

This module depends on

• openai-whisper (for local asr)
• torch&torchaudio for silero vad
  Most of the cuda packages come from torch installation.
  While openai-whisper could be optional, silero vad (or any vad) is required.
  One of the solutions would be to use onnx runtime for the silero vad https://github.com/snakers4/silero-vad
