Write multiple bytes to an SDIO card using IO_RW_EXTENDED (CMD53)

This function performs write operation using CMD53 in byte mode. For block mode, see sdmmc_io_write_blocks.

@param card pointer to card information structure previously initialized using sdmmc_card_init @param function IO function number @param addr byte address within IO function where writing starts @param src data to be written @param size number of bytes to write @return - ESP_OK on success - ESP_ERR_INVALID_SIZE if size exceeds 512 bytes - One of the error codes from SDMMC host controller
