Rasters API #5
Description
It doesn't look like there is an automated solution to get rasters in the way that we've obtained vectors, so we'd have to create a manual database of all links. Then, they are presented as zipfiles, meaning that we would have to use something like Scratch.jl and ZipFile.jl to unpack them manually and store them in a package-specific scratchspace. Assuming no name duplicates, this should also allow us to present a list of already-downloaded rasters.
