Add hume voices list and hume voices delete

[twitchard]

Notes:

• hume voices list defaults to listing custom voices. You specify --provider HUME_AI for shared voices.
• I changed hume tts "blah" --voice-name "VINCE DOUGLAS" --preset-voice to hume tts "blah" --voice-name "VINCE DOUGLAS" --provider HUME_AI for consistency with the API. Something about hume voices list --preset-voice seemed wrong to me.
