Partitioned heat conduction (G+Smo participant)

[Crazy-Rich-Meghan]

Summary: Partitioned heat conduction G+Smo (IsoGeometric Analysis) participant
NOTE: G+Smo adapter is a submodule of the G+Smo library, to run the tutorial you need to configure G+Smo main library.

• Updated README.md file, which contains instructions on how to configure G+Smo library with preCICE adapter.
• Added gismo-executable folder to contain the symbolic link for the G+Smo executable.

This PR is marked as a draft because the documentation for the G+Smo adapter requires updates.

Let's first iterate on #603 and then here, OK?

@Crazy-Rich-Meghan do you plan to continue this development? It seems to currently be in draft state. We are happy to help get it in a good state!

Hi everyone,

Sorry for the delay! I have updated the partitioned heat conduction example from our side, this version supports the direct mesh access feature. To run the benchmark you need to do the following:
1. Clone G+Smo
2. cmake .. -DCMAKE_BUILD_TYPE=Release -DGISMO_OPTIONAL="gsPreCICE"
3. cmake --build build --target partitioned-heat-conduction -j
4. Install this example systemwide make install partitioned-heat-conduction
5. Go to the neumann-gismo folder run the Neumann participant with the run script.
6. Go to the dirichlet-gismo folder run the Dirichlet participant with the run script.

Let me know if you get stuck somewhere!
