RelayerRequiredForPartialFill

A partial_fill was requested for an order whose relayer field is empty; partial fills are only permitted on orders that restrict who may execute them. Check the order payload and either set a relayer list or execute the full amount.

Declared by the LimitOrders pallet; it classifies to the semantic code invalid_argument.
