py-fonttools: updated to 4.38.0

4.38.0 (released 2022-10-21)
----------------------------

- [varLib.instancer] Added support for L4 instancing, i.e. moving the default \ 
value of
  an axis while keeping it variable. Thanks Behdad!
  It's now also possible to restrict an axis min/max values beyond the current \ 
default
  value, e.g. a font wght has min=100, def=400, max=900 and you want a partial \ 
VF that
  only varies between 500 and 700, you can now do that.
  You can either specify two min/max values (wght=500:700), and the new default \ 
will be
  set to either the minimum or maximum, depending on which one is closer to the \ 
current
  default (e.g. 500 in this case). Or you can specify three values (e.g. \ 
wght=500:600:700)
  to specify the new default value explicitly.
- [otlLib/featureVars] Set a few Count values so one doesn't need to compile the font
  to update them
- [varLib.models] Make extrapolation work for 2-master models as well where one \ 
master
  is at the default location
  Add optional extrapolate=False to normalizeLocation()
- [varLib.cff] Fixed sub-optimal packing of CFF2 deltas by no longer rounding them to
  integer
- [scaleUpem] Calculate numShorts in VarData after scale; handle CFF hintmasks
