Allow user to control number of tasks for ESMF_RegridWeightGen, which
easily throws a segmentation fault on too few processors. Use 512
cores when processing 2km source data.

Extrapolate 2D thermal forcing on source grid before remapping
to MALI mesh. This gets rid of missing values that were being
interpolated to the MALI mesh as 1e36.
Process runoff field for AIS, since we have it available and can
use it in face-melting.
