ci_prop_wald

Calculates the Wald interval by following the usual textbook definition
for a single proportion confidence interval using the normal approximation.

This calculates a variety of different CIs for proportions
and difference of proportions that are commonly used in the
pharmaceutical industry including Wald, Wilson, Clopper-Pearson,
Agresti-Coull and Jeffreys for proprotions. And Miettinen-Nurminen
(1985) <doi:10.1002/sim.4780040211>, Wald, Haldane, and Mee
<https://www.lexjansen.com/wuss/2016/127_Final_Paper_PDF.pdf> for
difference in proportions.
