- Update to v1.45
* Bugfix: minor planets and comets in Skyfield 1.44 would raise
an exception if asked for a position in the half of their orbit
where they are inbound towards their perihelion.
- Changelog v1.44
* Skyfield’s internal table for the ∆T Earth orientation
parameter has been updated, so that instead of including
measurements only through December 2021 it now knows Earth
orientation through September 2022.
* Distance and velocity objects can now be created by calling
their unit names as constructors, like d = Distance.km(5.0) and
v = Velocity.km_per_s(0.343).
* Updated the URL from which the Hipparcos database hip_main.dat
is downloaded, following a change in the domain for the
University of Strasbourg from u-strasbg.fr to unistra.fr.
