Code Review

This pull request adds support for input and output audio transcriptions in the command-line Python client. The CONFIG is updated to enable these features, and the receive_audio function now processes transcription data from the server, printing it to the console with specific formatting. Feedback was provided to ensure consistent newline handling for input transcriptions, matching the logic used for output transcriptions.
