Function tsxlib::timeutils::round_nearest_to_nearest_duration

pub fn round_nearest_to_nearest_duration<TDate>(
    timestamp: &TDate, 
    sample_size: &Duration
) -> TDate where
    TDate: DurationRoudable<TDate>, 

Max precision is milliseconds

Rounds a TDate to the nearest duration, i.e. if you had a chrono::NaiveDateTime{2020-12-31T12:35:00Z} and you rounding to Duration{15mins} it would return 12:30
