Add FANS to conda-forge

[claudiushaag]

Hi!

We would love to add our open-source Fourier Accelerated Nodal Solvers, (FANS) to conda-forge.
The package effectively just exposes an executable, FANS.
This is our first contribution, but we were able to build packages locally. We would love some feedback and are exited about adding FANS to the community!

The build problems here are not apparent using mambabuild locally.
They seem to be addressed here and here
But, mambabuild does not find the stdlib('c'). Thus, now trying to change to rattler-build...

@conda-forge/help-c-cpp ready for review!

[danielnachun]

Can you try enabling macOS here? I believe all of the dependencies are available, though I realize MPI is not terribly useful on a single macOS machine. However, there is still value for users to able to do simple local tests. OpenMPI support on Windows is lacking conda-forge at the moment so skipping that OS is understandable.

[claudiushaag]

@danielnachun Thank you for having a look at this!
Currently, the macOS build does not compile for us locally, but we're working on it: DataAnalyticsEngineering/FANS/pull/25
The same is valid for the CI.

My plan was to update that as soon as it is ready.

[claudiushaag]

I think this would be ready to merge, would appreciate it!
