`wrapdims` doesn't work when axis eltype is `UnitRange`

It works when the eltype is a tuple of ints, but not when it's a range.

julia> wrapdims(DataFrame(a=[(1,2), (3,4)], b=[10, 20], c=[100, 200]), :c, :a, :b)
2-dimensional KeyedArray(NamedDimsArray(...)) with keys:
↓   a ∈ 2-element Vector{Tuple{Int64, Int64}}
→   b ∈ 2-element Vector{Int64}
And data, 2×2 Matrix{Int64}:
            (10)  (20)
   (1, 2)    100     0
   (3, 4)      0   200

julia> wrapdims(DataFrame(a=[(1:2), (3:4)], b=[10, 20], c=[100, 200]), :c, :a, :b)

Reproduce the Julia example, then start in src/tables.jl at populate_function_barrier! and follow its calls into src/lookup.jl at findindex. Check how tuple-valued axis keys are handled versus Vector{UnitRange{Int64}}. Done means wrapdims accepts the range-valued axis column and produces the same key-to-value placement without the reported error.
