Deprecate FieldStatistics
FieldStatistics used the so-called naive algorithm to calculate various descriptive statistics. This means that is directly takes the mathematical definition of things like Mean = sum(x_i)/n and translate it into code (Reduce(x_i)/Reduce(1)), without any consideration of numerical precision. It has been discussed extensively in the literature how something as simple as summation is tricky in computer. This worklet should be deprecated once the replacement DescriptiveStatistics WIP is delievered.
