FFTViews breaks with loaded (PaddedViews | OffsetArrays)

[roflmaostc]

Hey,

ref PaddedViews breaks FFTViews #50

Similar happens with OffsetArrays:

julia> using FFTViews

julia> x = FFTView(ones((3)))
3-element FFTView{Float64, 1, Vector{Float64}} with indices URange(0,2):
 1.0
 1.0
 1.0

julia> x .+ 1
3-element FFTView{Float64, 1, Vector{Float64}} with indices URange(0,2):
 2.0
 2.0
 2.0

julia> using OffsetArrays

julia> x .+ 1

I've seen the comment regarding the composition of several types but that's the issue here, is it?

Thanks a lot!
