missing methods for label2ind

I get this ```julia julia> x=[1 0; 0 1] 2×2 Array{Int64,2}: 1 0 0 1 julia> label2ind(x, LabelEnc.OneOfK(2)) ERROR: MethodError: no method matching isposlabel(::Array{Int64,2}, ::MLLabelUtils.LabelEnc.OneOfK{Int64,2}) Closest candidates are: isposlabel(::Bool, ::MLLabelUtils.LabelEnc.OneOfK)...

I find convenient the following methods: ```julia onehot(x) = onehot(Int, x) onehot(T::Type, x) = convertlabel(LabelEnc.OneOfK{T}, x) ``` Worth the addition?
