Renamed function "calc_tilt_angle" to "calc_rotating_frame_params" in lib.rotating_frame.
Regarding sr #3124, (https://gna.org/support/index.php?3124) - Grace graphs production for R1rho analysis with R2_eff as function of Omega_eff.
This is to reflect, that the function should return and store spin values of both tilt_angles, Delta_omega and omega_eff.
