Documentation addition: Revise README.md (and/or the "help"/"how to use" feature from the CLI) with new instructions

[carmen-chau]

General list of additional information / instructions to add:

• If the user does not have models--pyannote--speaker-diarization-3.1 located in their .cache folder, then the CLI would download it first. This leads to a progress bar (with no label) showing up). Users should be made aware about this.

Picture reference:

• If the user does not have the desired whisper .pt file in their local .cache folder, then a progress bar would show up during the running of method define_whisper_model. There is no label to this progress bar, so users should be aware about what this progress bar is.

Picture for reference:
