Fixing spin contributions to orbital angular momentum in SpinTaylorTx precession equations

Description

This branch introduces new features into the SpinTaylor precession equations:

  • it introduces a flag that can switch on spin dependent term in the orbital angular momentum
  • it introduces a flag that can switch between orbital-averaged and instantaneous phasing and precessing equations

API Changes and Justification

Backwards Incompatible Changes

  • This change modifies an existing API
  • This change removes an existing API

The new features required a rationalization of the "XLALSimInspiralSpinTaylorTxCoeffs" structure and the addition of an input variable in XLALSimInspiralSpinTaylorPNEvolveOrbit(). Note however that XLALSimInspiralSpinTaylorPNEvolveOrbit() is wrapped in a backward-compatible way by XLALSimInspiralSpinTaylorDriver() and XLALSimInspiralSpinTaylorOrbitalDriver() and the use of XLALSimInspiralSpinTaylorPNEvolveOrbit() as external function is discouraged and should be discontinued.

This merge request replace the old !1412 (closed)
