About reduce memory usage

Since I'm using a resource-deficient MCU (ram: 20K), and I only use classic can,

So for the payload_buffer size in the structure Txitem, I can use CANARD_MTU_CAN_CLASSIC.

`define CANARD_MTU_CAN_CLASSIC 8U

define CANARD_MTU_CAN_FD 64U

define CANARD_MTU_MAX CANARD_MTU_CAN_FD

typedef struct TxItem { CanardTxQueueItem base; uint8_t payload_buffer[CANARD_MTU_MAX]; } TxItem; `

The payload_buffer field here is a flex array member; the declared size has no influence on its memory footprint.

Thanks for comments,

Sure, got it.
