Calculate XR-ratio tables

valid_XRratio() calculates the exchange rate ratio (XR-ratio), which is a region/country's XR-price for a product divided by the geometric mean of the product price. Variability can be compared to highlight products in countries/regions that are most variable (high XR-ratio) across countries.
