v2.0.4

Summary:
This release adds new capability for being able to find constituent files using glob strings when using definition files (Thanks @ludwigus for the suggestion!!). This capability required some refactorization within the software for how paths work (now using pathlib). This release also adds some higher resolution astronomical calculations for determining solid earth tides using ephemerides from JPL. A new timescale class has also been added for converting between different time standards, and between universal (UT) and dynamic (TT) time.
