Function etterna::find_fastest_note_subset_wife_pts

pub fn find_fastest_note_subset_wife_pts(
    seconds: &[f32], 
    min_num_notes: u32, 
    max_num_notes: u32, 
    wife_pts: &[f32]
) -> FastestComboInfo

This function finds the “best” note subset (where the number of notes in the subset is in min_num_notes..=max_num_notes). The function operates on a single lane only!

How is “best” defined? It’s NPS multiplied by Wife points. For example, a sequence of 50 notes in the timespan of 10 seconds, with a wifescore of 80% yields a value of 4.

The caller still has to scale the returned speed value by the music rate (only applies to etterna-graph, where the note seconds are always in 1.00x)

seconds must be sorted, and in the same order as wife_pts!
