Implement views of KroneckerArrays when slicing with cartesian products, which results in KroneckerArrays where the arguments are the corresponding views.
Along with recent developments in BlockSparseArrays.jl (ITensor/BlockSparseArrays.jl#157, ITensor/BlockSparseArrays.jl#156), this enables some blockwise slicing of block sparse arrays with Kronecker array blocks, though certain slicing operations are broken right now (which will be investigating in future PRs to BlockSparseArrays.jl and KroneckerArrays.jl).
