For Sudoku variants, given a boolean map for which ranks [1, 2, 3, 4, 5] are all discarded,
returns an array for these ranks of the longest play sequences starting at these maps (indexed 0
through 4), and a boolean stating whether all ranks are still available, i.e. whether the
returned array is [5, 5, 5, 5, 5]. This functions mimics the method sudokuWalkUpAll from the
server file "variants_sudoku.go".
