otherEntity (file) size and md5sum values missing for knb-lter-cap.724 and 725

[srearl]

The (file) size and md5sum values for an otherEntity (Jeff's script) were missing for both knb-lter-cap.724 and -725 in a second run through these datasets. This was not a problem on in an earlier run of these datasets, and only occurred after updating (1) write_units to include the QUDT description, and (2) allowing create_raster to use inputted attribute data (as opposed via yaml) but neither of these should have had any effect on creating an otherEntity. I could not reproduce this with a different dataset.
