Generate a python program that has the following intention:

The intention of the program is to find the next palindrome number in a given list of numbers. A palindrome number is a number that is the same when read forward and backward, such as 121 or 2020.

The function next_palindrome(number_list) takes a list of numbers as input and returns the next palindrome number in that list. The algorithm works by dividing the list in half and searching for the first two numbers that are equal to or greater than 10 and can be added to form a palindrome. The algorithm then adds 1 to these two numbers and updates the corresponding positions in the list. This process is repeated until a palindrome is found or until all the numbers in the list have been processed.

The program is intended to be used when given a list of numbers that is not a palindrome, such as [1, 2, 3, 4, 5, 6], and the goal is to find the next palindrome number that can be formed from those numbers. The program will return [1, 2, 3, 4, 4, 5, 6, 7, 8, 7, 6, 5, 4, 3, 2, 1, 0] as the next palindrome number, which is 4454.
