This merge implements TaylorF2+ and TaylorF2Quasi, both are improved point-particle baselines for the TaylorF2 model. TaylorF2+ extends TaylorF2 by incorporating higher-order PN terms up to 6PN over a range of 10-1500Hz. TaylorF2Quasi implements corrections up to 5.5PN based on Taylor expanding the factorised and resummed EOB energy fluxes and taking the SPA.
If any of the Backwards Incompatible check boxes are ticked please provide a justification why this change is necessary and why it needs to be done in a backwards incompatible way.
Awaiting final review sign-off.
