Cartesian::to_frame rotates a state between orientations sharing a center,
velocity included: v' = R v + R_dot r. A test pins it against physics, since
a point fixed to the equator moves at omega*r inertially. ANISE's DCM is
f64, so the matrices are lifted into the propagated scalar; the rotation
depends on epoch and not state, so that is also the right derivative.
Geodetic converts to and from a body-fixed position and gives the local
east-north-up rotation. The height form is the one that survives the poles.
Adds pck11.pca, which reopens body-fixed frames for bodies other than Earth
and lets our body constants be checked against the kernel's. It is fetched
from storage.googleapis.com because public-data.nyxspace.com serves a
certificate that does not cover its own name.
