[feat] Add laser id for livox mid360

Livox Mid-360 packet doesn't provide information of laser id. See here.

But points are ranged in the order of laser line numbers. (0, 1, 2, 3, 0, 1, 2, 3...)

So we can get laser_id by computing point_id % 4. (Mid-360 has 4 laser lines)

• Add laser id for livox HAP. It seems like that HAP has 5 laser lines. To be checked
