PR Summary

• Refactor of cli.py File
  This pull request involves key changes made to the cli.py file, an important component of our software.

• Updated Import Statements
  The import statement from .utils import filename, str2bool, write_srt was updated to from utils import filename, str2bool, write_srt. This change improves how our code accesses essential utility functions.

• Advanced Function Parameters
  The transcribe function was called with additional arguments, namely initial_prompt="prompt" and word_timestamps=True. This modification enables more direct interaction with the transcription process and timestamps for each word in the text, making our output more detailed and informative.

• Replace Function Call
  The write_srt function was replaced with the get_writer function along with the filename extension "srt" and options detailed in a dictionary. This transition enhances our ability to create subtitles in a more efficient and adaptive manner.

• Enhanced User Feedback Messages
  Print statements have been added to display the output path and the message "Generating subtitles for {filename(path)}... This might take a while." These improvements enrich our user feedback system, enhancing the user experience by providing more detailed status updates during the subtitle generation process.
