Scheduled weekly dependency update for week 50

[pyup-bot]

Update fonttools from 4.14.0 to 4.18.1.

Changelog

4.18.1

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

- [colorLib] Speed optimization for ``LayerV1ListBuilder`` (2119).
- [mutator] Fixed missing tab in ``interpolate_cff2_metrics`` (0957dc7a).

4.18.0

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

- [COLRv1] Update to latest draft: added ``PaintRotate`` and ``PaintSkew`` (2118).
- [woff2] Support new ``brotlicffi`` bindings for PyPy (2117).
- [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 (2114).
- [subset] Allow ``LangSys`` tags in ``--layout-scripts`` option (2112). 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 (2107).
- [feaLib] You can export ``FONTTOOLS_LOOKUP_DEBUGGING=1`` to enable feature file
debugging info stored in ``Debg`` table (2106).
- [otlLib] Build more efficient format 1 and format 2 contextual lookups whenever
possible (2101).

4.17.1

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

- [colorLib] Fixed regression in 4.17.0 when building COLR v0 table; when color
layers are stored in UFO lib plist, we can't distinguish tuples from lists so
we need to accept either types (e5439eb9, googlefonts/ufo2ft/issues426).

4.17.0

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

- [colorLib/otData] Updated to latest draft ``COLR`` v1 spec (2092).
- [svgLib] Fixed parsing error when arc commands' boolean flags are not separated
by space or comma (2094).
- [varLib] Interpret empty non-default glyphs as 'missing', if the default glyph is
not empty (2082).
- [feaLib.builder] Only stash lookup location for ``Debg`` if ``Builder.buildLookups_``
has cooperated (2065, 2067).
- [varLib] Fixed bug in VarStore optimizer (2073, 2083).
- [varLib] Add designspace lib key for custom feavar feature tag (2080).
- Add HashPointPen adapted from psautohint. With this pen, a hash value of a glyph
can be computed, which can later be used to detect glyph changes (2005).

4.16.1

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

- [varLib.instancer] Fixed ``TypeError`` exception when instantiating a VF with
a GSUB table 1.1 in which ``FeatureVariations`` attribute is present but set to
``None`` -- indicating that optional ``FeatureVariations`` is missing (2077).
- [glifLib] Make ``x`` and ``y`` attributes of the ``point`` element required
even when validation is turned off, and raise a meaningful ``GlifLibError``
message when that happens (2075).

4.16.0

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

- [removeOverlaps] Added new module and ``removeOverlaps`` function that merges
overlapping contours and components in TrueType glyphs. It requires the
`skia-pathops <https://github.com/fonttools/skia-pathops>`__ module.
Note that removing overlaps invalidates the TrueType hinting (2068).
- [varLib.instancer] Added ``--remove-overlaps`` command-line option.
The ``overlap`` option in ``instantiateVariableFont`` now takes an ``OverlapMode``
enum: 0: KEEP_AND_DONT_SET_FLAGS, 1: KEEP_AND_SET_FLAGS (default), and 2: REMOVE.
The latter is equivalent to calling ``removeOverlaps`` on the generated static
instance. The option continues to accept ``bool`` value for backward compatibility.

4.15.0

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

- [plistlib] Added typing annotations to plistlib module. Set up mypy static
typechecker to run automatically on CI (2061).
- [ttLib] Implement private ``Debg`` table, a reverse-DNS namespaced JSON dict.
- [feaLib] Optionally add an entry into the ``Debg`` table with the original
lookup name (if any), feature name / script / language combination (if any),
and original source filename and line location. Annotate the ttx output for
a lookup with the information from the Debg table (2052).
- [sfnt] Disabled checksum checking by default in ``SFNTReader`` (2058).
- [Docs] Document ``mtiLib`` module (2027).
- [varLib.interpolatable] Added checks for contour node count and operation type
of each node (2054).
- [ttLib] Added API to register custom table packer/unpacker classes (2055).
