Bump fonttools from 4.21.1 to 4.22.1

[dependabot]

Bumps fonttools from 4.21.1 to 4.22.1.

Release notes

Sourced from fonttools's releases.

4.22.1

• [feaLib] Skip references to named lookups if the lookup block definition is empty, similarly to makeotf. This also fixes an AttributeError while generating aalt feature (#2276, #2277).
• [subset] Fixed bug with --no-hinting implementation for Device tables (#2272, #2275). The previous code was alwyas dropping Device tables if no-hinting was requested, but some Device tables (DeltaFormat=0x8000) are also used to encode variation indices and need to be retained.
• [otBase] Fixed bug in getting the ValueRecordSize when decompiling MVAR table with lazy=True (#2273, #2274).
• [varLib/glyf/gvar] Optimized and simplified GlyphCoordinates and TupleVariation classes, use bytearray where possible, refactored phantom-points calculations. We measured about 30% speedup in total time of loading master ttfs, building gvar, and saving (#2261, #2266).
• [subset] Fixed AssertionError while pruning unused CPAL palettes when 0xFFFF is present (#2257, #2259).

4.22.0

• [ttLib] Remove .Format from Coverage, ClassDef, SingleSubst, LigatureSubst, AlternateSubst, MultipleSubst (#2238). ATTENTION: This will change your TTX dumps!
• [misc.arrayTools] move Vector to its own submodule, and rewrite as a tuple subclass (#2201).
• [docs] Added a terminology section for varLib (#2209).
• [varLib] Move rounding to VariationModel, to avoid error accumulation from multiple deltas (#2214)
• [varLib] Explain merge errors in more human-friendly terms (#2223, #2226)
• [otlLib] Correct some documentation (#2225)
• [varLib/otlLib] Allow merging into VariationFont without first saving GPOS PairPos2 (#2229)
• [subset] Improve PairPosFormat2 subsetting (#2221)
• [ttLib] TTFont.save: create file on disk as late as possible (#2253)
• [cffLib] Add missing CFF2 dict operators LanguageGroup and ExpansionFactor (#2249) ATTENTION: This will change your TTX dumps!
