- Expose FT_Outline_Decompose() as Outline.decompose() (thanks duelafn)
- `examples/glyph-vector-decompose.py`: Use larger size, and with FT_LOAD_NO_BITMAP, to avoid loading embedded bitmaps (thanks HinTak)
- `Glyph.get_cbox`: unbreak (thanks fpgayu)
- Improve variable font support with examples (thanks josh-hadley)
- Update embedded FreeType and HarfBuzz in wheels to latest versions.
- Drop Python 2 support and 32 bit wheels.

Testing the new CI...

* Remove Python 3.7 CI builds, we don't actually need them.

* Update bundled FreeType to 2.10.0
* Update bundled HarfBuzz to 2.3.1
* Add Python 3.7 builds to PyPI
* Removed `FT_Outline_{New,Done}_Internal` functions, as these were only accidentally exposed in the public API.
* `FT_Face` can now be instantiated with a file path or a byte stream from memory
* Fix bug where outline and bitmap could be off by one grid unit in one of the examples, when extrema did not have on-curve points.
* Corrected the license classifier, the project is BSD licensed.
