Not the best workaround, but if you are already using Firefox (or similar fork), you can start the download in Firefox, cancel the download, and right-click on the entry in the Downloads pane and select "Copy Download Link" to get the direct url. Then you can do something like this in the terminal:
curl --output [filename.ext] -X GET [url]
(This is for the individual files, the "Download all files" link works with curl. I haven't tested it with other utilities, but it will probably work too.)
