      Description

      The size of a Wcs pickle increased in DM-7152 (due to this commit). It needs to be reduced so as to maximise the number of inputs a coadd may have (since a list of Wcs is transmitted over the wire in the coaddDriver, and pickle in python 2 has a size that must fit in an int); we are hitting the limit when coadding Cosmos y-band data from HSC.
