Rotates all components of a seismogram.
The components will be rotated from ZNE (Z, North, East, left-handed) to LQT (e.g. ray coordinate system, right-handed). The rotation angles are given as the back-azimuth and inclination.
The transformation consists of 3 steps:
1. mirroring of E-component at ZN plain: ZNE -> ZNW
2. negative rotation of coordinate system around Z-axis with angle ba:
ZNW -> ZRT
3. negative rotation of coordinate system around T-axis with angle inc:
ZRT -> LQT
