Design a Python class named LibraryItem to represent items in a library with the following attributes and methods:

Attributes:

$.$ item$\_$id $($integer$)$: An ID for the library item $($default $0).$

title $($string$)$: The title of the item $($default "Unknown"$).$

checked$\_$out $($boolean$)$: A flag indicating if the item is currently checked out $($default False$).$

$-$due$\_$date $($string$)$: The due date for the item $($default "Not Checked Out"$).$

$-$late$\_$fee$\_$per$\_$day $($float$)$: The late fee per day for the item $($default $0\mathrm{.}0).$

Methods:

$.($self$,$ item$\_$id$,$ title$)$: A constructor that initializes the library item with the specified item ID$,$ and title.

$.$check$\_$out$($self$,$ due$\_$date$)$: A method that allows a library user to check out the item. It should set the checked$\_$out flag to True and update the due$\_$date attribute with the provided due date.

$-$display$\_$info$($self$)$: A method that returns a string containing information about the library item in the following format: "Item ID: item$\_$id$,$ Title: title, Checked Out: checked$\_$out, Due Date: due$\_$date".

Write a test program that does the following:

Create a LibraryItem object representing a book with an item ID of $123,$ a title of "The Great Gatsby".

Use the check$\_$out method to check out the book with a due date of $"2023-10-15".$

Print the information of the library item using the display$\_$info method.

Example Output:

Item ID: $123,$ Title: The Great Gatsby, Checked Out: False, Due Date: $2023-10-15$

Constraints:

$-$The item$\_$id should be a positive integer.

$-$The title should be a non$-$empty string.
