No module named 'pkg_resources' error caused by recent update of setuptools

Hello, I just wanted to report that I had to add a specification of the `setuptools` version, as shown below. This is likely due to an issue in setuptools <https://github.com/pypa/setuptools/issues/5174>.

```
mamba create -n fpocketR -c bioconda fpocketr 'setuptools<82'
conda activate fpocketR
```

Otherwise, when I ran the code, I received an error message:
> No module named 'pkg_resources'
