This is a set of changes that enables exact restart tests to pass with FATES, for
        longer periods, particularly those that have elapsed over a year.
        We removed calls that were incrementing, uncecessary calls, and added key new
        variables to the restart file (such as the leaf layer carbon balance vector).
