These were previously in ESMPy but should be here in part because ESMPy is now noarch: python.

@ocefpaf, please have a look when you have time. @zklaus, if you are back from your time off, please have a look as well.

@rokuingh, I'm not sure what your availability is but you're welcome to take a look, of course.

@ocefpaf, wow! I wasn't aware of downstream tests. Let's see how it goes...

@ocefpaf, that doesn't seem to have worked:

Mamba failed to solve:
 - esmpy 8.4.2.* pyhc1e730c_1
 - esmf 8.4.2.*

 - python >=3.7
 - esmf 8.4.2.* mpi_mpich_*

The reported errors are:

It seems like it's trying to test with mpich, regardless of the actual MPI build.

It seems like it's trying to test with mpich, regardless of the actual MPI build.

Sorry for the bad suggestion. Let's avoid the test/downstream for now to get this fix in. I'll do some research on how to fix this later.

[xylar]

Okay, I'll remove my last commit.
