"""Unpickle from FITS
Unpack data produced by `reduceToFits`. This method is used by the
pickling framework and should not need to be called from user code.
Parameters
----------
cls : `type`
the class of object to unpickle. Must have a class-level ``readFits``
method taking a `~lsst.afw.fits.MemFileManager`.
data : `bytes`
an in-memory representation of the object, compatible with
`~lsst.afw.fits.MemFileManager`
size : `int`
the length of `data`

-------
unpickled : ``cls``
the object represented by ``data``
