/api/openai-voicemap API endpoint

Can call /api/openai-voicemap with 

curl -X PUT "http://localhost:7851/api/openai-voicemap" -H "Content-Type: application/json" -d "{\"alloy\":\"female_01.wav\",\"echo\":\"female_01.wav\",\"fable\":\"female_01.wav\",\"nova\":\"female_01.wav\",\"onyx\":\"male_01.wav\",\"shimmer\":\"male_02.wav\"}"

Caveats:

- You have to update all the voices in one go, not just one voice.
- Its up to you to ensure you have the correct voices for the TTS engine that's loaded in which you can find currently available on /api/voices
- The in-memory mappings will update, but Gradio will have cached what was originally in the settings, so it wont display the changes in the Gradio interface without a restart of AllTalk/Gradio
