Is your feature request related to a problem? Please describe

Sometimes datasets are stored as folders of images, where each folder is a single multidimensional image and within it are a series of 2D (or 2D with channels) images, e.g. single page TIFFs or PNGs, each of which is a position in Z or T.

Describe the solution you'd like

• Be able to upload a folder of images (an image series) as a single multidimensional image
• Be able to upload a folder of folders, each of which is an image series, as a collection of multidimensional image

Describe alternatives you've considered

We could just make people do this with third party tools but it's fairly common so we should support it.
