Standard Error of from Confidence Intervals of Odds Ratio

Calculates the standard error from an odds ratio confidence interval.

This method uses multiple steps in the background:
1 Takes odds ratio (OR) limits and transforms them to log(OR)
2 Calculates the standard error for the log(OR)
3 Transforms the log(OR) standard error to standardized mean differences (SMD) standard error by multiplying it with sqrt(3)/pi
