Standard statistics using Welford's algorithm

 Statistics::Welford provides standard statistics (mean value,
 variance, standard deviation, minimum and maximum value as well as
 the number of elements) using Welford's algorithm.
 Welford's algorithm is much more resource efficient compared to the
 naïve algorithm implemented in e.g. Statistics::Basic::StdDev or
 Catmandu::Fix::stat_stddev. It especially does not need to load all
 values into RAM at the same time, i.e. does not require an array
 containing all values.
