Update fonttools from 3.44.0 to 4.0.0.

Changelog

4.0.0

---------------------------

- NOTE: The v4.x version series only supports Python 3.6 or greater. You can keep
using fonttools 3.x if you need support for Python 2.
- [py23] Removed all the python2-only code since it is no longer reachable, thus
unused; only the Python3 symbols were kept, but these are no-op. The module is now
DEPRECATED and will removed in the future.
- [ttLib] Fixed UnboundLocalError for empty loca/glyph tables (1680). Also, allow
the glyf table to be incomplete when dumping to XML (1681).
- [varLib.models] Fixed KeyError while sorting masters and there are no on-axis for
a given axis (38a8eb0e).
- [cffLib] Make sure glyph names are unique (1699).
- [feaLib] Fix feature parser to correctly handle octal numbers (1700).
