When trying to use **StatsBase.modes** of result of MLJ model fit I get error -  
`ERROR: MethodError: no method matching iterate(::UnivariateFinite{Multiclass{2}, String, UInt32, Float64})`  
However if I use **StatsBase.mode** everything works fine

`The input is the same input - UnivariateFiniteVector{Multiclass{2}, String, UInt32, Float64}`

Indeed, `StatsBase.modes` is not overloaded for objects of type `CategoricalDistributions.UnivariateFinite` - only `mode` is.

I have opened a feature request here:
