Feature request: Choose which elements to display and add weekdays as a new element

[Frakcool]

I'd like to be able to display weekdays inside the scrolls and decide if I want to display for example year or maybe number of days

Something like:

MON | TUE | WED | THUR | FRI | SAT | SUN
   1     |    2   |    3    |     4        5   |    6   |    7
JAN   | ....

And a method like:

func displayElements(_ elements: [ElementType]) {
    //Logic here
}

That would be called like:

datePicker.displayElements([.weekday, .day, .month])

The code above would display weekdays, days and months

While this one below would display only months and years:

datePicker.displayElements([.month, .year])
