measurements 875 --> 936 in session JUN '18 OCL
somehow got filled with beam off data.
camera, spectra and current measurements all show beam off yet sample, capture ID and timestamp info all count up as expected.
In fact the beam was not off for these measurements, but somehow stale data got into the files?
it shouldn't be possible to re-write stale data. to prevent this we could compute hashes over every dataset we take and compare the new dataset's hash to the previous one to ensure that it's unique data
