This should download from the ingest cache (#138). At a minimum, if the ingest pipeline is running it should ensure that files exist.
Eventually, I assume that this will run on in some sort of fresh/serverless way, so it may not be necessary to check file dates - but we may do that anyway, once there is support in the downloader code.
Closing this as an external downloader rather than depending on a cache. We will likely implement the cache (and maybe soon), but we likely can postpone that until a little later.
