Text to Speech Widget PR

I’ve played around with Speech Synthesis in the browser, created a SpeechSynthesis widget and contributed it as a PR to Panel.

See https://github.com/holoviz/panel/pull/1878

Watch the video (and remember to turn on sound :slight_smile:)

If you have ideas for use cases or improvements I would really like to hear them. Thanks.

UPDATE: SpeechSynthesis widget renamed to TextToSpeech widget
