Engelbadge for DiVOC: Push to Talk

Based on card10s RainName app, auto app switching when [Timer](https://badge.team/projects/timer) or alarm of [Control Center](https://badge.team/projects/control_center) goes off is also included.

[Your angel name is set in nickname.txt or nickname.json in card10s root directory](https://card10.badge.events.ccc.de/en/gettingstarted/#:~:text=setting%20your%20nickname)

You can press the TOP_RIGHT_BUTTON to push the button and watch the button animation and led the bottom leds light up.
If your firmware supports it, you can also use it to send a key press (default: media stop) and hopefully you can map this button somehow as your push to talk button.

Of course it also displays date (=day of event) and time.
