Some external flash modules have extra commands to support, for example, reading/writing an OTP zone. Given that the commands are highly specific and difficult to generalize, we add two ex ops that can be used to transmit a custom command (in the form of a full QSPI_CommandTypeDef) and then read or write a user-provided buffer.
