Add DataFrame.parallel_map and Dataframe.parallel_agg

Maybe Dataframe.parallel_applymap is removed in future, but I left it there for compatibility.

@nalepae I tried to add a few new functions and changed the github actions (removed old python versions). I don't know how to setup the workflow perfect. At the moment Test for old pandas versions will fail due to the new numpy version (for pandas <2.0 numpy <2.0 is required). It would be nice if you could have a look on this pull request.
