### QC
<!-- Make sure that you can tick the boxes below. -->

* [x] I confirm that I have followed the [documentation for contributing
to
`snakemake-wrappers`](https://snakemake-wrappers.readthedocs.io/en/stable/contributing.html).

While the contributions guidelines are more extensive, please
particularly ensure that:
* [x] `test.py` was updated to call any added or updated example rules
in a `Snakefile`
* [x] `input:` and `output:` file paths in the rules can be chosen
arbitrarily
* [x] wherever possible, command line arguments are inferred and set
automatically (e.g. based on file extensions in `input:` or `output:`)
* [x] temporary files are either written to a unique hidden folder in
the working directory, or (better) stored where the Python function
`tempfile.gettempdir()` points to
* [x] the `meta.yaml` contains a link to the documentation of the
respective tool or command under `url:`
* [x] conda environments use a minimal amount of channels and packages,
in recommended ordering
