BLE extended advertising parsing

Hello Team ST,

I am currently working on parsing my extended BLE data using the BLE_p2pClient_Ext application, specifically the `analyse_ext_adv_report` function to view the advertising data. However, I am having trouble parsing and appending the full extended advertising data. Could you please assist me with this issue?

Thank you in advance.

Here is my modified function.

static uint8_t analyse_ext_adv_report(hci_le_extended_advertising_report_event_rp0 *p_ext_adv_report) {
 uint8_t status;
 
 if ((display_filter != 0) && HAL_IS_BIT_SET(p_ext_adv_report->Event_Type, 0x0010)) {
 status = 1;
 } else {
 status = 0;
 
 l_buff_pos = 0;
 memset(&l_buff[l_buff_pos], 0, L_BUFF_SIZE);

 l_buff_pos += snprintf(&l_buff[l_buff_pos], L_BUFF_SIZE - l_buff_pos, 
 "%02X:%02X:%02X:%02X:%02X:%02X | ", 
 p_ext_adv_report->Address[5], p_ext_adv_report->Address[4],
 p_ext_adv_report->Address[3], p_ext_adv_report->Address[2],
 p_ext_adv_report->Address[1], p_ext_adv_report->Address[0]);

 // Check for legacy or extended advertisement
 if (HAL_IS_BIT_SET(p_ext_adv_report->Event_Type, 0x0010)) {
 l_buff_pos += snprintf(&l_buff[l_buff_pos], L_BUFF_SIZE, "LEGACY |");
 } else {
 l_buff_pos += snprintf(&l_buff[l_buff_pos], L_BUFF_SIZE, "EXTENDED |");
 }

 l_buff_pos += snprintf(&l_buff[l_buff_pos], L_BUFF_SIZE - l_buff_pos, "%4d | ", (int8_t)p_ext_adv_report->RSSI);
