Falwa

This minor release include a fix in graph plot procedure `scripts/nhn_grl2022/graph_plot_module.py` - the plotting script for the residual plot is fixed such that it produces the same plot on different machines.

This is a minor release that fixes the issues with `setup.py` that cannot locate the compiled fortran modules. Thanks chpolste for fixing this!

The archive on PyPI has also been also fixed in v0.6.5.

This release includes the fix for the calculation of meridional flux component. See the [correction note](https://github.com/csyhuang/hn2016_falwa/blob/aa45499fcfb0bdc0236f93b39c83bd9f68ef9abb/notes/LWA-budget-on-the-sphere-revised-20221230.pdf) for details. The corrigendum on Neal et al 2022, GRL corresponds to this release.

The main change in the calculation can be found in this commit: 38d95f6202f2b0d052263437a61124fe3ace0d65

Please remove all the compiled fortran modules on your machine and `git pull` the newest version of fortran codes for installation (`python setup.py develop`).

There were resolution-dependent procedures which worked with the (360x181) grid we used for NHN2022, GRL. This bugfix enables the new inversion routine to take data of other grid sizes.

Major update:

- Thanks Christopher Polster chpolste for developing an **xarray interface** for the QGField object using the SOR solver to compute reference state as documented in [Nakamura and Huang (2018, Science)](https://www.science.org/doi/abs/10.1126/science.aat0721).
- Sample code that use this interface: `examples/nh2018_science/demo_script_for_nh2018_with_xarray.ipynb`
- Please refer to the corresponding [xarray interface documentation](https://hn2016-falwa.readthedocs.io/en/latest/Xarray%20Interface.html) page for details.

Minor update:

- Added `.gitignore` for this repo
- Fix documentation display on readthedocs.io
- Fortran code files are now moved to `hn2016_falwa/f90_modules/` such that the compiled `.so` modules are located in `hn2016_falwa/`
- Cleaned up f2py modules and remove unused variables

to fields at the equator, which improves the quality of the analysis.

The analysis code to reproduce results in Neal et al. "The 2021 Pacific Northwest heat wave and associated blocking: Meteorology and the role of an upstream cyclone as a diabatic source of wave activity" (submitted to GRL) can be found in the directory `scripts/nhn_grl2022/`.
