enhancement and bugfix.

[serkansmg]

this part was buggy..
`

/* Extract target 2 data from the frame */
sensorData = extractData(TARGET_2, position);
if (sensorData.x != 0)
{
m_callback(TARGET_2, sensorData);// it was TARGET_3
}

`

and i add 2 feature to sensorData

`

Ld2450::SensorData Ld2450::extractData(SensorTarget target,
DataPosition position)
{
SensorData sensorData;

int offset = (target * 8); // each target 8 bytes
sensorData.x =
    ((int16_t)position.start[offset + 1] << 8) | position.start[offset + 0];
if (position.start[offset + 1] & 0x80)
  sensorData.x = -sensorData.x + 0x8000;
sensorData.y = (position.start[offset + 3] << 8 | position.start[offset + 2]);
if (sensorData.y != 0)
  sensorData.y -= 0x8000;
sensorData.speed =
    position.start[offset + 5] << 8 | position.start[offset + 4];
if (position.start[offset + 5] & 0x80)
  sensorData.speed = -sensorData.speed + 0x8000;
sensorData.resolution =
    position.start[offset + 7] << 8 | position.start[offset + 6];
    //calculate distance
     sensorData.distance = sqrt(sensorData.x * sensorData.x + sensorData.y * sensorData.y);
     sensorData.angle = atan2(sensorData.y, sensorData.x) * 180.0 / M_PI;
    

return sensorData;

}`

and sensor data is now:
`

struct SensorData
{
int x;
int y;
int speed;
int resolution;
double distance;
double angle;
};
`

also added:
`
/**
* @brief Get the current tracking mode
*
* @returns 0 - single target, 1 - multi target
*/
bool getTargetTrackingMode(uint8_t &mode); //to .h file

//to .cpp
bool Ld2450::getTargetTrackingMode(uint8_t &mode)
{

sendCommand(Ld2450Commands::GET_TARGET, nullptr, 0);
return getAckFrame(DELAY_MS, [&](const DataPosition &pos)
                   {
                     if ((pos.end - pos.start) < 8)
                     {
                       return; // sainty check
                     }
                    ESP_LOGI(TAG, "getTargetTrackingMode Target tracking mode: %d", pos.start[6]);
                     //set mode
                      mode = pos.start[6]; });

}

`

i can create a pull request or you may add these.. or i can fork .. its up to you..
cheers..
