feat: Add a flag to hide the description

[beyarkay]

This commit adds a flag to not show any of the event descriptions, like a summary view.

Some calendars have really long event descriptions containing links and all sorts of garbage. It's super handy to just see the event name. Consider:

                This event shows that there will be loadshedding on Sunday from 16:00 to Sunday at 18:00 in the load shedding area buffalo-city-block-1.

                When new loadshedding schedules are announced, your calendar will be automatically updated to show when your power will be off.

                While these new schedules are calculated immediately, it can sometimes take a bit of time for your calendar app (ie Google Calendar, Apple iCalendar, or Outlook) to fetch the updated schedules. Often you can set the update frequency in the settings of your calendar app.

    18:00-19:00 ⚠️  End of schedule
                This is the end of the known loadshedding schedule.

                Unfortunately only a few days worth of loadshedding schedules are released at a time. An update to the loadshedding schedule is usually announced a day or two before the previous schedule runs out, so this event will move in your calendar as new schedules are announced.

                You don't have to do anything, but just know that there might be loadshedding after this point, but there also might not. It's impossible to say for sure.

The former is quite a bit more readable.
