December updates

poliastro wishes everyone a merry new revolution around the Sun! 💫

During the December break, Juan Luis wrote a new example on how to read OMM and TLE data that will help with a number of typical satellite observation use cases and merged a few refactors and cleanups of the source code. We expect to make a 0.16.1 release soon to ship the documentation improvements, and will keep cleaning up the code over the coming weeks and addressing some long-standing issues.

In addition, Sebastian will kick off the project to add array types to poliastro very soon. This work will be possible thanks to the generous funding of NumFOCUS, and will improve the performance of the library for some use cases.
