Some scalar functions are available in Datafusion version 30.0.0. Maybe we should first update our datafusion version. block by https://github.com/apache/arrow-datafusion-python/pull/464

• isnan
• iszero

Great! Most of the array functions have been done but not completely. I'm not going to add more functions to my PR, so feel free to contribute to any functions that are not implemented.

I think most of the remaining ones are covered in #605
