v1.0.0 Release of python package `falwa` v1.0.0

1. The python package is renamed from hn2016_falwa to falwa #91
2. There is a fix in code for zonal advective flux computation. The correction done in release 0.7.2 happens to be an over-correction. See #92 for mathematical details. Thanks Christopher Polster for spotting the error. The fix requires re-compilation of fortran modules.
3. QGDataset now supports dataset with even number of latitude gridpoints #85
4. User can delay the return of variable from methods in QGField/QGDataset by the boolean parameter return_named_tuple.
5. Cartopy is replacing Basemap (deprecated) in all the visualization examples #87
6. The GitHub workflow has been updated and run successfully #82
