py-fonttools: updated to 4.18.2

4.18.2 (released 2020-12-16)
----------------------------
- [COLRv1] Implemented ``PaintTranslate`` paint format.
- [varLib.cff] Fixed unbound local variable error.
- [otlLib] Don't crash when creating OpenType class definitions if some glyphs
  occur more than once.

4.18.1 (released 2020-12-09)
----------------------------
- [colorLib] Speed optimization for ``LayerV1ListBuilder``.
- [mutator] Fixed missing tab in ``interpolate_cff2_metrics`` (0957dc7a).

4.18.0 (released 2020-12-04)
----------------------------
- [COLRv1] Update to latest draft: added ``PaintRotate`` and ``PaintSkew``.
- [woff2] Support new ``brotlicffi`` bindings for PyPy.
- [glifLib] Added ``expectContentsFile`` parameter to ``GlyphSet``, for use when
  reading existing UFOs, to comply with the specification stating that a
  ``contents.plist`` file must exist in a glyph set.
- [subset] Allow ``LangSys`` tags in ``--layout-scripts`` option. For example:
  ``--layout-scripts=arab.dflt,arab.URD,latn``; this will keep ``DefaultLangSys``
  and ``URD`` language for ``arab`` script, and all languages for ``latn`` script.
- [varLib.interpolatable] Allow UFOs to be checked; report open paths, non existant
  glyphs; add a ``--json`` option to produce a machine-readable list of
  incompatibilities
- [pens] Added ``QuartzPen`` to create ``CGPath`` from glyph outlines on macOS.
  Requires pyobjc.
- [feaLib] You can export ``FONTTOOLS_LOOKUP_DEBUGGING=1`` to enable feature file
  debugging info stored in ``Debg`` table.
- [otlLib] Build more efficient format 1 and format 2 contextual lookups whenever
  possible
