Med-res visits from EngRun12 are wrongly labelled as low-res

Just got reminded of a nasty book-keeping issue.
While we were taking the fiberProfiles dataset, I though it'd be smart to start to move the grating(s) after the shutters close, while we were reading the detector, to save a bit of time.
But as a result, some med-res data has been wrongly labelled as low-res which non only impact the headers but also the filename itself.
I'm not quite sure how to fix this properly.

Perhaps, to avoid this kind of trouble, maybe we should freeze the resolution at the beginning of the exposure, if possible cloomis ?
