`Distributions.jl` and `RecursiveArrayTools.jl` do not work together.

Hi! Thanks for this great package.

When I am training to construct a Categorical Distribution with an ArrayPartition vector it fails with a conversion error.

using RecursiveArrayTools
using Distributions

Categorical(ArrayPartition([1/3, 1/3], [1/3]))

Error

ERROR: MethodError: Cannot `convert` an object of type Vector{Float64} to an object of type ArrayPartition{Float64, Tuple{Vector{Float64}, Vector{Float64}}}

Closest candidates are:
  convert(::Type{ArrayPartition{T, S}}, ::ArrayPartition{<:Any, <:Tuple{Vararg{Any, N}}}) where {N, T, S<:Tuple{Vararg{Any, N}}}
