RasterStack does not load lazily with directory path as argument

[tiemvanderdeure]

When loading a RasterStack using the directory path containing the rasters instead of filenames, the Rasters are loaded to disk even when using lazy = true.

An example reproducing this is:

using Rasters, ArchGDAL

r = Raster(rand(100, 100), dims = (X(1:100), Y(1:100)), missingval = NaN)

dir = "mydata"

if ~isdir(dir) mkdir(dir) end

for i in 1:10
    write("$dir/raster_$i.tif", r)
end

stack = RasterStack(dir, lazy = true)

Rasters.isdisk(stack) ## false!

files = ["$dir/raster_$i.tif" for i in 1:10]
stack = RasterStack(files, lazy = true)
Rasters.isdisk(raster1) ## true
