refactor: Update whisper version and add extra models

[royshil]

The audio processing delay calculation in the process_audio_from_buffer function has been updated. The duration of the audio processing is now compared to the remaining delay, and if it exceeds the delay, the delay is increased by 100 milliseconds. Otherwise, the delay is decreased by 100 milliseconds.

refactor: Update model information retrieval

The code for retrieving model information in the cleanstream_properties function has been updated. The loop that adds models to the list now uses the models_info() function instead of the models_info map directly.

refactor: Update whisper model update logic

The logic for updating the whisper model in the update_whisper_model function has been updated. The models_info() function is now used to check if the new model path exists in the models_info map. Additionally, the models_info().at(new_model_path) function is used to retrieve the model information.

refactor: Update model downloader types

The models_info map has been changed to a function models_info() that returns a constant reference to the map. The get_sorted_models_info function has also been added to retrieve a sorted vector of model information.

refactor: Update prebuilt whispercpp version

The prebuilt whispercpp version in the BuildWhispercpp.cmake file has been updated to version 0.0.7. The download URL has also been updated to the new repository location.
