This is a re-publication of the metadata of Harvard's DASCH
plate scans to obscore.

This is based on a data/plates.csv that we got via mail from Peter
Williams.  We read the plate ids from there and use the DASCH API;
API docs at https://docs.api.starglass.cfa.harvard.edu/, human-written
docs are at https://starglass.cfa.harvard.edu/docs/api/mosaics.html.

To do manual API calls, use something like
curl -v -H"x-api-key: `cat dasch-api-key`" https://api.starglass.cfa.harvard.edu/public/plates/p/a01299/download

The test set is the metadata of the plates a01299 through a01854.
