Add a button to facilitate sharing of downscaled registered projects, for the sake of building automated registration models

[NicoKiaru]

It would be nice to have a simple button that would generate a small zip containing all the information required in the optics of training a an automated registration model.

What I image is the following:

• all images downscaled to 10 micron resolution
• unregistered original image data (2D only)
• resampled registered image data to 10 um
• selection by the user of a subset of channels to avoid sharing irrelevant data for the registration
• atlas name
• generation date
• user description
• user contact
• lab contact
• data share agreement (potentially delegated to Zenodo)
• one or several hash to avoid duplicates
• registration info:
  • atlas slicing angle
  • affine registration
  • spline registration (optional)

Potentially follow quicknii +visualign format

Where to share these data easily ? Zenodo looks like a good fit, a community could be created to collect all of these
