RoundedNormalAllPositionsManipulator applies bounds incorrectly

Description

Since RoundFeasible was introduced, which takes care of transforming each dimension into a feasible value, part of the old transformation code was left over, which leads to wrong manipulations:

int value = (vector[i] + (int)Math.Round((N.NextDouble() * sigma[i % sigma.Length])) - min) / step; // transformation 1
max = FloorFeasible(min, max, step, max - 1);
vector[i] = RoundFeasible(min, max, step, value); // transformation 2
