add instructions for kokoro

[d4v3y0rk]

Adding documentation for using a new local model for generating TTS audio. the project is Kokoro-FastAPI. It uses a new model recently released and sounds pretty great and works seamlessly since it implements the openai api for speech generation. I am using it in my setup already.

Perhaps the voice options available from the Kokoro TTS Demo Gradio WebUI page should be mentioned, which include:

af
af_bella
af_nicole
af_sarah
af_sky
am_adam
am_michael
bf_emma
bf_isabella
bf_george
bf_lewis
