This commit allows the frequency-dependent drag to be implemented in tensor form, by incorporating the off-diagonal components of the wave drag tensor into the MOM_wave_drag module.

This is part of the Pull Request I opened earlier (#961), but is relevant to the frequency-dependent drag only.

I have a few minor and specific changes that I think would make this commit slightly better, which I have described in separate specific comments, but once they are in place I think that this PR will be ready to go.
