FB-LTS Hurricane Test Case

[jeremy-lilly]

This PR creates a version of the Hurricane Sandy test case from #618 for a new LTS scheme called FB-LTS -- see E3SM-Project/E3SM#6224.

Plots comparing the sea-surface height predicted by FB-LTS versus that predicted by LTS are given below.

Using the E3SM PR E3SM-Project/E3SM#6224 I was able to run this test case on both perlmutter and chicoma and produce the plots above. Thanks @jeremy-lilly for your great work!

@jeremy-lilly could you check the user's guide here
https://mpas-dev.github.io/compass/latest/users_guide/ocean/test_groups/hurricane.html
which may be edited in this file:
https://github.com/MPAS-Dev/compass/blob/main/docs/users_guide/ocean/test_groups/hurricane.rst
and see if there is a place to add some description of the fblts option? Thanks.

[jeremy-lilly]

Thanks @mark-petersen! I've fixed the git history by removing that merge to main, committing a change to the docs, and the rebasing to main. Let me know if that doesn't look right!

[mark-petersen]

Thanks! The rebase and added notes to the doc page look good. I tested again with intel on chrysalis and gnu on perlmutter to be sure, and everything works!

@jeremy-lilly, the E3SM-Project submodule has finally been updated in #821 to bring in the changes you need. Could you rebase (again) to include that? Then, I'll run the tests and (hopefully) approve and merge.

[jeremy-lilly]

@xylar, I just rebased! Please let me know if anything doesn't look right. Thanks!

Tests are passing on Chrysalis (Intel/OpenMPI):

and the documentation looks good.
