accumulate function missing?

[leios]

julia> a = ROCArray(ones(10,10))
10×10 ROCMatrix{Float64}:

┌ Warning: Performing scalar indexing on task Task (runnable) @0x00007f984a1fc010.
│ Invocation of getindex resulted in scalar indexing of a GPU array.
│ This is typically caused by calling an iterating implementation of a method.
│ Such implementations *do not* execute on the GPU, but very slowly on the CPU,
│ and therefore are only permitted from the REPL for prototyping purposes.
│ If you did intend to index this array, annotate the caller with @allowscalar.

I believe we should be able to just copy the accumulate functionality in CUDA: https://github.com/JuliaGPU/CUDA.jl/blob/master/src/accumulate.jl

I'll give this a go soon
