Configuration File #2
Description
While the atsdata.json file is embedded into https://github.com/kcphysics/ATSPythonUtils, it is not necessarily going to be the most up to date. While the ATSPythonUtils project can stand this, as configuring command line utilities on each read would be a pain, the API does initialize everytime it starts.
Move configurations off to a JSON file for loading the data on the system, and it falls back to using the one embedded in ATSPythonUtils.
This should have, at least, the atsdb key, where it can read the nav database.
