py-smote-variants: Added package py-smote-variants (#42502)

* py-smote-variants: Added package py-smote-variants

Also added py-minisom and py-metric-learn as dependencies

* py-metric-learn: Added build dependency on setuptools

* py-smote-variants: Added a dependency on py-pytest-runner

As well as a comment about why statistics isn't included

* [@spackbot] updating style on behalf of alex391
