Zig interface with EventKit

[Uzaaft]

EventKit provides access to the calendar and reminders for macOS.

As a basic MVP, a wrapper around this should handle:

• List calendar entries
• Create calendar entries
• Remove calendar entries

Events, Reminders and alarms can be handled post MVP

https://github.com/colbyhall/objective-zig seems to be a wrapper around zig and objc that includes supports for EventKit. Not yet tested. A litmus test could be to test if this can fetch all the events thats in a calender.

Failed litmus test
