Type of buffer in `read!` is too restricted

[felixcremer]

When I try to plot a Raster which is based on an ArchGDAL overview array this does not work because I can't read! into a PermutedDims array. See rafaqz/Rasters.jl#596.

Can we expand the type that read! accepts so that we could read also into AbstractMatrix and not only Matrix?

Possible that ArchGDAL.jl is passing that to C? In which case Array is really needed.

Yes, they are being passed to C (but I can also see that it is too type-restrictive in some settings)
