Function meeting_dates 

pub(crate) fn meeting_dates(
    bank: &str,
    start: NaiveDate,
    end: NaiveDate,
    schedule: Option<PyRef<'_, PyMeetingSchedule>>,
) -> PyResult<Vec<NaiveDate>>

The dates bank’s policy decisions take effect between start and end inclusive — the dates a step curve’s meeting knots land on — from the given schedule or the seeded one ("FED", "ECB", "BOE").
