Add new feature in BitCrack -- 3

I need added in BitCrack a functionality to partition the key range into an X amount of partitions and process them in parallel using the existing logic without affecting the performance and saving the progress and continuing from where it was left(it already has this logic but needs adapted for the partitioning feature, for example if I want to partition the key range in 1 trillion partitions to save the progress every minute like it does now)
