- use `r.in.pdal` from core (drop outdated addon)
    - update `-s` flag to `-g` in Dockerfile and test
- OpenMP support: yes
- grass-session test enabled
- use `grass --tmp-location XY` for `--exec` calls (suggested by @wenzeslaus in https://github.com/OSGeo/grass/pull/2073#pullrequestreview-924640702)
- install `py3-scikit-learn` for `r.learn.ml2` addon
