User guide for use in React projects

1. Install @ricky0123/vad-react:

   npm i @ricky0123/vad-react

2. Follow the bundling instructions for @ricky0123/vad-web. To recap, you need to serve the worklet and onnx files that come distributed with @ricky0123/vad-web and the wasm files from onnxruntime-web, which will both be pulled in as dependencies.

3. Use the useMicVAD hook to start the voice activity detector:

   import { useMicVAD } from "@ricky0123/vad-react"
   
   const MyComponent = () => {
     const vad = useMicVAD({
       startOnLoad: true,
       onSpeechEnd: (audio) => {
         console.log("User stopped talking")
       },
     })
     return <div>{vad.userSpeaking && "User is speaking"}</div>
   }

   See the docs for useMicVAD for details.
