Improved accuracy
This release fixes alot of stuff. The highlights:
- Earth nutation and TT-UT1 correction terms are now automatically downloaded and applied to coordinate conversions, so the user doesn't have to.
- Computed planet positions are now more accurate for the SOFA algorithm.
- The Autotools build system has been fixed, although it is now deprecated and will be removed in a future release.
- Actual code tests and coverage checks have been created and are run on all pull requests.
