✨ Add reset_metadata parameter to .load()

[Marigold]

Fix for #3724 (comment)

ds.load(reset_metadata=True) lets you load a dataset and reset all its metadata (origins, titles, etc.). This is especially useful when working with population table. Division by population could propagate unwanted metadata such as presentation.title_public.

Nice!

Would it be possible to have the option to preserve the origins? I've had a go in this PR. I was thinking we probably still want to record in the origins when we've used population (etc) to create a new variable, but it's the other parts of the VariableMeta() that we would want to be rid of.
