Galore

-------------------------------------------------------------------------
- Fix galore-plot-cs import error (ajjackson)

-------------------------------------------------------------------------
(galore-plot-cs is broken in this release - use 0.9.2)

- Deal with matplotlib compatibility issues (ajjackson)

- 3.6 deprecation/rename of seaborn-colorblind
- Use public API to get line colour more robustly

- Deal with scipy deprecation of polyval (kavanase)

-----------------------------------------------------------------------------------
- Minimum Python version has increased to 3.8
- Allow --xflip to be used with simple 1-d data plots (ajjackson)
- BUGFIX: Import type annoations from collection.abc. This is required
for Python 3.10, which deprecates the original location. (Hashan-Peiris)

-----------------------------------------------------------------------------------
- Minimum Python version has increased to 3.7
- Orbital-projected plots have gained pretty fill colours; these are
controlled by `--no-fill`, `--no-total`, `--alpha` and
`--legend-cutoff` command-line options. (kavanase)

-----------------------------------------------------------------------------------
- Continuous integration has been migrated from Travis to Github Actions
- Minimum Python version has been increased to 3.5.

- Python 3.4 was not available through Github actions. It is not wise to
support a platform we cannot test.

- BUGFIX: missing import affecting process_pdos

-----------------------------------------------------------------------------------
- Updated setup.py to add a [vasp] extra; this handles Pymatgen
installation which can be tricky on older Python versions.
- Update the [vasp] extra to handle some compatibility breaks between
dependencies and different Python versions.
- Fix some incorrect values in Al k-alpha XPS cross-sections
- BUGFIX: Pymatgen CompleteDOS was not correctly accepted by galore.process_pdos()
- Implement previously ineffective "offset" option in
galore.plot.plot_pdos(), add a matching option to
galore.plot.plot_tdos()
