cpld_control_wave test does not have waves turned on -> OCN; run fails if waves->OCN is on

[DeniseWorthen]

Description

The cpld_control_wave test was added in PR #379 (6a4c307). At that time, it did not use the setting MOM6_USE_WAVES=True. The basic test remained unchanged at PR #765 (4e7a72e) when it was updated to the P7 configuration and renamed cpld_control_wave_p7.

Setting MOM6_USE_WAVES=True causes the cpld_control_wave_p7 test to fail with a seg fault.

To Reproduce:

Run the cpld_control_wave_p7 from the current develop branch. The run succeeds. Examining the PET logs for the Ocn (eg. PET160) shows that none of the partitioned stokes drift components are connected as imports to the ocean. The INPUT/MOM_input setting for USE_WAVES is set to False.

Copy the run directory into a test directory and change the variable USE_WAVES to True. Submit the job. The PET160 log shows that Ocn is expecting the stokes drift components as imports (they are connected). However, the run fails with the following:

@DeniseWorthen I actually ran into this same problem last night when I tried to change that in the defaults. The solution is to add:
&OUTS USSP = 1, IUSSP = 3, STK_WN = 0.04, 0.110, 0.3305 /
to the ww3_grid.inp input files, which will require a new input directory which is currently staged here:
/scratch1/NCEPDEV/nems/emc.nemspara/RT/NEMSfv3gfs/input-data-20210930/WW3_input_data_20211113
I plan to include this in PR#911 just have a few more non-wave tests that are breaking due to the changed defaults to sort out before I merge all my changes back to that branch and that PR is ready.

How come my run did not crash? I had "USE_WAVES = True" in MOM_input

The low resolution (1 deg) configuration uses a different grid file than the higher resolution (1/2deg) used with the 1/4 deg ocean resolution. The cpld_bmark_p7 runs fine.
