[SOFA] Returns the Celestial Intermediate Pole

,
`x`

coordinates for the given TT Julian Date
`y`

, based on IAU 2006 precession and IAU 2000A
nutation. The output variables have the same dimensions as
`jdtt`

.
`jdtt`

The

and `x`

coordinates are those of the
unit vector towards the celestial intermediate pole. They represent
the combined effects of frame bias, precession, and nutation.
