Summary

Added cancel_orders_batch extrinsic to allow lp to close multiple orders at the same time (up to 100)
Added cancel_orders_batch and cancel_all_orders to the LP API, the latter simply query for all the open orders and then submit a cancel_orders_batch, in case the open orders are more than 100 it will submit multiple extrinsics with batch of 100 orders each (if the WaitFor parameter is set to InBlock or Finalized the extrinsics will be split across multiple blocks)

The events emitted are the same as before (RangeOrderUpdated, LimitOrderUpdated), there will be one event for each order being closed, in case an order passed is not correct (wrong orderId or the order was fully filled before the extrinsic is executed) the deletion of that order is skipped and a new event OrderDeletionFailed { order: CloseOrder } is emitted.
