Add elastic-tube-1d rust solvers

[fsimonis]

This PR is based on #434 and adds elastic-tube-1d rust solvers.

As long as cargo is installed, they can be run solely by running ./run.sh.
VTK output and plotting is supported.

Rust bindings for version 3 are released. You can now run them straight away.

---

To run these solvers locally, you need to replace the bindings release with the develop version.

In elastic-tube-1d/{solid,fluid}-rust/Cargo.toml change:

 [dependencies]
-"precice" = 3
+"precice" = { git = "https://github.com/precice/rust-bindings.git" }

Then run.sh as usual.

I'll merge the solvers now. We can always iterate on them later.
