Edit Order Book

When there is no limit order on the order book, the user can modify the two parameters of minimum amount and price step
The order book also has two parameters, the protocol fee and the GAS subsidy fee, which can only be modified by the administrator at present. It will be opened to the community later, and the community will vote to decide. By default, the protocol fee is 0.3%, which is paid by the ordering party. If it is some special token pair, such as when both tokens are stable coins, you can contact the project party to change the protocol fee to 0.1%, and the GAS subsidy fee defaults to 50% of the protocol fee
