Add an alternative stream initialization in the app generator.

Hi @qlambert-pro !

Thanks so much for this !!! And sorry I took so long to handle it. I was doing a big refactoring.

In the end I opted for a simpler solution than passing in a dummy stream : just a comment to tell people to comment out the code :

            const initApp = async () => {
                // Register the worklet
                await WebPdRuntime.initialize(audioContext)

                // Fetch the patch code
                response = await fetch('${compiledPatchFilename}')
                patch = await ${artefacts.compiledJs ? 
                    'response.text()': 'response.arrayBuffer()'}

                // Comment this if you don't need audio input
                stream = await navigator.mediaDevices.getUserMedia({ audio: true })

                // Hide loading and show start button
                loadingDiv.style.display = 'none'
                startButton.style.display = 'block'
            }

            const startApp = async () => {
                // AudioContext needs to be resumed on click to protects users 
                // from being spammed with autoplay.
                // See : https://github.com/WebAudio/web-audio-api/issues/345
                if (audioContext.state === 'suspended') {
                    audioContext.resume()
                }

                // Setup web audio graph
                webpdNode = await WebPdRuntime.run(
                    audioContext, 
                    patch, 
                    WebPdRuntime.createDefaultSettings('./${compiledPatchFilename}'),
                )
                webpdNode.connect(audioContext.destination)

                // Comment this if you don't need audio input
                const sourceNode = audioContext.createMediaStreamSource(stream)
                sourceNode.connect(webpdNode)

                // Hide the start button
                startButton.style.display = 'none'
            }

But thanks so much again :wink:
