Hi! I can add add the Modern Polars tests raised in issue #1945 . I created a draft of a single example to make sure this is in line with what you're looking for. In this particular example, modin and pure pyarrow aren't implemented. According to the issue, you'd like me to raise these as new issues so they can be implemented right?

Once this is clarified I can go through and add the rest of the examples, there aren't that many.

hi @tylerriccio33 is this still active? IMO we can merge these tests incrementally, we don't need to do it all in one go
