Function sc_consensus_slots::slot_lenience_exponential

pub fn slot_lenience_exponential(
    parent_slot: u64, 
    slot_info: &SlotInfo
) -> Option<Duration>

Calculate a slot duration lenience based on the number of missed slots from current to parent. If the number of skipped slots is greated than 0 this method will apply an exponential backoff of at most 2^7 * slot_duration, if no slots were skipped this method will return None.
