    ticks_to_wait: TickType_t

@brief Do a SPI transaction

Essentially does the same as spi_slave_queue_trans followed by spi_slave_get_trans_result. Do not use this when there is still a transaction queued that hasn’t been finalized using spi_slave_get_trans_result.

@param host SPI peripheral to that is acting as a slave @param trans_desc Pointer to variable able to contain a pointer to the description of the transaction that is executed. Not const because we may want to write status back into the transaction description. @param ticks_to_wait Ticks to wait until there’s a returned item; use portMAX_DELAY to never time out. @return - ESP_ERR_INVALID_ARG if parameter is invalid - ESP_OK on success
