Transforms LiDAR from one horizontal datum to another using either a NTv2 grid or a seven parameter helmert transform.

Note that there are two ways of specifying the rotational part of the Helmert transform. The Position Vector Transformation (PVR) convention and the Coordinate Frame Rotation (CFR) convention.
The difference between them is that their rotation matrix is of opposite orientation. You need to specify in the command line which of the two you are using by adding either ‘-pvr’ and ‘-cfr’ to the command line.
