new parameter allowing to use the same model for both realtime and final transcriptions:

use_main_model_for_realtime (bool, default=False)

If set to True, the main transcription model will be used for both regular and real-time transcription. If False, a separate model specified by realtime_model_type will be used for real-time transcription.

Using a single model can save memory and potentially improve performance, but may not be optimized for real-time processing. Using separate models allows for a smaller, faster model for real-time transcription while keeping a more accurate model for final transcription.
