Calendar-driven do-not-disturb switch

1. Automate Community
2. Productivity

Set a calendar containing events during which you want to have your device muted (except priority) and it will automatically set your sound profile based on contained events.
Fixed version as Andreas Gustavsson pointed out some mistakes. Hope it works better now.

If you cancel/delete an event during the event, the flow will not correct itself until another event is reached. I might add a fix to that in the future aswell. Until then, just add a dummy event in the next few minutes to fix the thing.

If you run into issues while cancelling an ongoing event, just restart the flow. If you need to cancel the DnD setting early, you really need to find the correct mode to disable it manually, there are more DnD modes and the one you can easily turn on in the volume settings is not the one this flow uses. (I might change it in the future, though)
