I tried installing concentration using pipx (`pipx install
concentration`) as well as compiling it (`poetry install`). In both
cases, it failed with the following error:

```

Note: This error originates from the build backend, and is likely not a problem with poetry but with pyyaml (6.0) not supporting P
EP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "pyyaml (==6.0)"'.
```

On Googling, I found the same stack-trace in
python-poetry/poetry#8287, and also an
associated fix: Upgrading PyYaml to 6.0.1

I did that using `poetry add pyyaml`, which fixed the problem.

This PR contains the changes to the lock file due to the `poetry add
pyyaml` command.
