Disable popups/alerts on errors

[luicfrr]

Please follow the general troubleshooting steps first:

• [x] Is your app running over HTTPS? (please provide the URL if possible) - https://serene-meerkat-95a23d.netlify.app/
• [x] Have you tried running the demo (https://codepen.io/mozmorris/pen/JLZdoP) on your device?
• [x] Checked the latest "Can I use" compatbility table? (https://caniuse.com/stream)

Features:

Would be nice if we could disable popups/alerts windows just passing a parameter to component:

    <Webcam
        ref={ webcamRef }

        disablePopups={true}  <--------- this prop here

        screenshotFormat='image/jpeg'
        onUserMedia={ handleWebca }
        onUserMediaError={ handleWebcamError }
      />

This is usefull when we are already handling errors using onUserMediaError
