Issue Description

I've found the bug with setting the initial date. If the initial date is not today when swiping right will lead not to the next day, but to today one. I've found out that this most likely happens because in TimelineContainerController TimelineView instance is set with today. I've experienced it in both my project (which is built on SwiftUI) and example.

Code I'm using with CalendarKit


override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    move(to: myDate)
}

Result I am trying to achieve

Change the initial date when showing the calendar and get correct swiping behavior.

What happens

The initial date is shown as needed, but swiping right will scroll not to the NEXT date, but today one.
