Missing S keyword for opRestriction

[nHackel]

Hello, I've run into an issue where the opRestriction and in turn the opExtension constructors don't have an S keyword argument. While the operator on its own works with GPU arrays, this causes an issue when trying to build composite ops for a GPU:

julia> using LinearOperators, CUDA

julia> x = CUDA.rand(256);

julia> op = opRestriction(1:128, 256);

julia> op * x # works

julia> (op * opDiagonal(x)) * x # fails

[dpo]

Could you please show the error message?

The error is:

julia> (op * opDiagonal(x)) * x
ERROR: LinearOperatorException("storage types cannot be promoted to a concrete type")

The storage_type of opRestriction is always Vector{Int64} without the added kwarg from #324
