feat: add optional json_output param to support JSON response

[himynameisben]

Description

This pull request updates the generate_podcast and process_content function in client.py to include an optional parameter for returning a JSON dictionary with detailed output information. If the parameter is not used, the function retains its original behavior to ensure backward compatibility.

Changes Made

Updated the generate_podcast function to collect the paths of the transcript and audio files.
Modified the return value of the generate_podcast function to be a JSON string containing the paths to the transcript and audio files.

Example JSON Output

{
  "transcript_file": "path/to/transcript.txt",
  "audio_file": "path/to/audio.mp3"
}

Files Modified

client.py

Testing

Verified that the generate_podcast function returns the correct JSON output with the paths to the transcript and audio files.
Ensured that the function handles cases where only a transcript is generated or both transcript and audio are generated.

Please review the changes and provide feedback. Thank you!
