Description
This function imports a SpatRaster image using terra::rast() functionality, and divide into four masks, using the image centre and borders as vertices.
The four zonal masks are then returned as a RasterStack.

zonal_mask(img)
Arguments
img
SpatRaster. The input single layer image generated from terra::rast().
