added solid solver based on the python bindings for Dune-Fem

[NiklasKotarsky]

New solid solver for the tutorial flow over heated plate. The solver uses Dune-fem's python bindings https://www.dune-project.org/sphinx/dune-fem/. Joint work with @uekerman and @dr-robertk. Code base inspired from https://github.com/PeterMeisrimel/asynch-WFR.

Thanks, @NiklasKotarsky 👍

Is this a duplication of #270 or an extension?
If you want to continue here, we should close the other one then.

[NiklasKotarsky]

Ok, I have extended #270 to also include implicit coupling.

Thanks a lot for contributing! Not sure what the state of it is, but when you are ready for a review, please also include some documentation in the README.md of the parent folder. Please also extend the PR description with a few more details.

Great work, thanks for adding this 👍

Also added the "adapter" to the website: precice/precice.github.io#173

I ran the tutorial and it seems to work 👍 Only problem for me was that I really needed to use a virtual environment, something our users may not be familiar with as well.

Note that one needs to make pyprecice and scipy available as well, e.g., with installing them again in the environment. By default, we ask users to install with pip3 install --user.

Thanks a lot for the contribution, this tutorial is shaping up really nicely! 😄
