Is your feature request related to a problem? Please describe.
LazyFrames are a feature of polars, where things are lazily evaluated. This is similar to pyspark, and thus extracting columns doesn't make sense, but a @with_columns decorator does.

Describe the solution you'd like
Add lazyFrame support with @with_columns.

Describe alternatives you've considered
You just manually do this all now.
