DataAPI.combine? Since DD owns one of the types...

It doesn't exist yet JuliaData/DataAPI.jl#65 ;)

This PR introduces a
combinemethod to make things like this easier:combine(f, groupby(dim_array_or_stack, Ti=month); dims=Ti)It helps with recomposing grouped output into a single DimArray/DimStack allowing for partial reductions of the grouped content.
Surprisingly hardly any code needed to do this, once I actually fixed
similarto make more sense on DimStack, and a few bugs insetindex!on stacks. I guess in the past it wasn't totally clear how these things should work. But makingcombinejust work like this for arrays or stacks probably means the design is correct now.similarnow matchesNamedTupleeltypes as layer types, and keeps the same dimension structure as the original stack (layers missing dimensions are still missing dimensions aftersimilar).
