Axes for transposed OffsetArray vector incorrect due to LinearAlgebra method #339

Just opening this to track the underlying Julia issue: https://github.com/JuliaLang/julia/issues/52373

Okay, so I suppose it's a bit bigger than that. Julia Base's issue is assuming that a transposed array will always have a 1-indexed first dimension. And it's true that OffsetArrays assumes that all nonspecified dimensions have the range 1:1.

I suppose my suggestion is that all unspecified dimensions should have a 0:0 range. But that would probably be considered breaking. So I'm open to other thoughts.

At a minimum, it would be nice if centered could produce an object that was centered along all dimensions. Its docstring does suggest that is the intended outcome.
