Swap out create_dev_dandiset for a dandi-cli based script

[waxlamp]

Original discussion comes from this comment.

Essentially, create_dev_dandiset bypasses the usual way of uploading assets to a dandiset and has some significant differences that resulted in a divergence between dev and prod (so to speak). A script that uses the same approach as real users to create a dev dandiset will help to avoid such divergences in the future.

@mvandenburgh, I've assigned us both to this issue, but you can certainly take the lead on it. I'd request you to show me what you come up with to solve this, or even pull me in to a planning session if you find that helpful.
