1995 split cases collection

[iamleeg]

This does all the stuff to make sure that GISAID/other excluded sources don't get into the cases collection, and reverts to using find() queries instead of aggregations for looking up cases which is sometimes hundreds of times faster.

What is doesn't do is migrate any of the existing data: AFAICT the only impact is that there's GISAID data in dev so we can delete and re-import if needed. No impact on prod.

@abhidg @jim-sheldon fixed the date filtering now, this should be ready to go.

Not sure about the package-lock.json diff (lockfileVersion changed, maybe due to different npm version?) other than that, looks good.
