Multiple issues on macOS on latest

[dimitre]

I've noticed the check for define _MACOS was not enough to auto detect macos, so I've changed to #elif defined(__APPLE__)
But then I found some errors due to non existent function
grabScanData
Looking for the objects I changed to grabScanDataHq, and rplidar_response_measurement_node_t -> rplidar_response_measurement_node_hq_t

and found the members are invalid

nodes[i].sync_quality
nodes[i].angle_q6_checkbit
nodes[i].distance_q2

but I don't know if they are equivalent now

sl_u16   angle_z_q14;
sl_u32   dist_mm_q2;
sl_u8    quality;
sl_u8    flag;

after this changes I had to change

std::string getSerialPath() const { serial_path_; }

to

std::string getSerialPath() const { return serial_path_; }

Is this right? or you will put back grabScanData ? thank you
