fix(growth): use centile and percentile correctly
1. The calculation made in `Grownth.Calc.Centile.compute/4` converts a
   given z-score into the expected measurement value.
   This can be used to get specific values for key z-scores, such as,
   -3, -2, 2 and 3.
2. To calculate the percentile of a given z-score the system uses the
   cumulative distribution function.
