Is there a Julia function that returns the UTM zone when given a latitude and longitude similar to Matlab’s [utmzone](https://www.mathworks.com/help/map/ref/utmzone.html)?

There’s a [`utm_zone`](https://github.com/JuliaGeo/Geodesy.jl/blob/master/src/utm.jl) function in the Geodesy.jl package. I think it does exactly what you’re looking for, but it does one better than Matlab’s `utmzone` by including the special rules for Svalbard.
