Force stop of page tree traversal when max level reached
The previous implementation, FindPDFPage, was already doing this since the recursive call was always with return. Currently, we were trying to keep going even after reaching max level. The problem is that if the page tree is not a tree, we might loop forever. This could also be solved by keeping track of the dictionaries that have been visited, but this solution takes much less space.
