rawview hides AxisArray

[Tokazama]

Currently rawview doesn't returns a MappedArray that doesn't have access to some of AxisArray's methods.

using TestImages
mri = testimage("mri");
axisnames(rawview(channelview(mri)))

I would prefer that axis information isn't removed from the the "raw view" of the Array. Is this an issue with the current implementation of rawview or should I being using something else?

"Threading" such operations is a perpetual problem. Until there's a better solution we might need to add some @require statements to special-case this kind of thing.
