[JessicaMeixner-NOAA]

Pull Request Summary

This PR updates ww3_gint to optionally interpolate restart files.

Description

This updates ww3_gint to interpolate restart files as an option. This is selected via the input file by ww3_gint.inp in the first line to now have the last option:
Time, time increment and number of outputs, and optional T/F -- option (default is T) to indicate out_grd (T) or restart (F)
A new set of regression tests for this is added:

./bin/run_cmake_test -b slurm -o all -S -T -s MPI_OMPH -w work_c -m grdset_c -f -p srun -n 140  -t 4 ../model ww3_ufs1.2
mkdir -p ww3_ufs1.2/work_l
cp ww3_ufs1.2/work_c/restart.hafsl ww3_ufs1.2/work_l/restart.hafsl
./bin/run_cmake_test -b slurm -o all -S -T -s MPI_OMPH -w work_l -m grdset_l -f -p srun -n 140  -t 4 ../model ww3_ufs1.2

which shows the use case of initializing a regional system from a global system.
