* Updated the typehints for itertools. * Removed the overload because it caused problems and cleaned up the imports. * Update itertools.pyi Added back optionality of second argument for itertools.permutations. * Update itertools.pyi Moved the Optional which I accidentially put on the wrong function -.-
