ModbusRtuReadWrite 方法

使用0x17功能码来实现同时写入并读取数据的操作，使用一条报文来实现，需要指定读取的地址，长度，写入的地址，写入的数据信息，返回读取的结果数据。
Use 0x17 function code to write and read data at the same time, and use a message to implement it, you need to specify the read address, length, written address, written data information, and return the read result data.
