pfw06, jdtt, gamb, phib, psib, epsa

[SOFA] Returns the IAU 2006 precession angles for TT Julian Date jdtt in Fukushima-Williams 4-angle formulation: f-w angle gamma_bar in radians gamb, f-w angle phi_bar in radians phib, f-w angle psi_bar in radians psib, f-w angle epsilon_a in radians epsa. The four output variables get the same dimensions as jdtt.
