Issue Description

I need DayHeaderView but I don't need the whole CalendarKit.

Result I am trying to achieve

Just connect DayHeaderView to my code directly. I have already added its UI but I don't understand how to connect its protocols/callbacks to my code

1. You need to store and hold the DayViewState object somewhere in your parent view, for example, the way it's done with the DayView: https://github.com/richardtop/CalendarKit/blob/master/Sources/DayView.swift#L56-L61
2. This is because the state property in the header is held weakly in order to avoid memory leaks: https://github.com/richardtop/CalendarKit/blob/master/Sources/Header/DayHeaderView.swift#L10-L18

Therefore, the moment you configure the state, it's being deallocated and you cannot control the header with it. You should hold the DayViewState somewhere else in your code. Please provide the code for reference.

additionally found out that it is a Observer pattern and I need to "subscribe" to events (public func subscribe(client: DayViewStateUpdating))

Correct, it's the Observer pattern. Hope you've fixed your issues, don't hesitate to ask if you need some help.
