Error handling

[zzarcon]

Different error might happen while trying to play the audio:

• Malformed src
• src pointing to a remote file without CORS
• autoPlay: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes

We should handle those accordingly and notify consumer:

import MicDrop from 'react-micdrop'

<MicDrop 
  src="nope"
  isPlaying={this.state.isPlaying}
  onError={() => this.setState({isPlaying: false})}
/>
