Dataframe partition method

[ratmice]

Is your feature request related to a problem or challenge?

Currently I use do a couple of dataframe.filter calls, when a single pass might be more efficient

let matches_df = df.clone().filter(expr.clone());
let inverse_matches_df = df.clone().filter(expr.is_not_true());

It could be nice if there was a function let (matches_df, inverse_matches_df) = df.partition(expr);
if it could produce both dataframes in a single pass from the filter expression.

Describe the solution you'd like

Describe alternatives you've considered

The running two filters does actually work, but a dedicated function might be clearer and could be more efficient.
