autobuild cmake/meson python/matlab

• move CI to Github Actions
• autobuild cmake or meson, with python or matlab/octave
• make modularization more robust
• improve test coverage

Build with Meson or CMake

For Python use Meson or CMake.

Matlab/Octave are still CMake, let us know if you want Meson.

Robust Matlab/Python API, integrate latest IRI2016 Fortran code

Cleaning house:

• cleanup Matlab/Python access to command-line Fortran API, necessitated by instabilities in original IRI2016 code.
• automatic CMake build as part of Python or Matlab install--required CMake ≥ 3.13
• add TEC simulation

Enhance unit tests, docs, and Matlab interface

NOTE: Matlab must be restarted to make more than one IRI2016 call. Or do repeated calls to Python front-end. Reloading Python module doesn't work.

This is due to old Fortran 77 coding techniques.

Rename, increase test coverage, add Matlab example

PyIRI2016=>IRI2016

modernize, standarize, cross-compiler compatibility

More cleanup to

• work with several Fortran compilers
• add Windows CI
• make command line scripts useful
• pep8, mypy, setup.cfg, markdown

Rework Fortran import system to be more efficient and robust

Thanks to @w2naf feedback, reworked import system and improved test coverage for top-level scripts.

Vast API cleanup, incorporation of simple, powerful xarray API

v1.4.0

functionalize plotting

simplify API, optional prereqs

v1.3.1

v1.3.1

API Cleanup

• Use datetime instead of individual time part variables.
• Make default verbosity off
• note deprecated basemap TODO update to cartopy
