Python 3.11 support

[sztamas]

Not sure if this is all that is need to support Python 3.11, but it might help in getting python-crfsuite work on Python 3.11.

• regenerated CPP files on Python 3.11 (as PyFrameObject fields changed on Python 3.11)
• added Python 3.11 to the tox config

Fixes #150

$ tox
  ...
  py27: OK (17.06=setup[16.45]+cmd[0.61] seconds)
  py36: SKIP (0.80 seconds)
  py37: SKIP (0.68 seconds)
  py38: SKIP (0.69 seconds)
  py39: SKIP (0.74 seconds)
  py310: OK (14.60=setup[14.07]+cmd[0.53] seconds)
  py311: OK (12.84=setup[12.39]+cmd[0.45] seconds)
  congratulations :) (47.62 seconds)

Error reported in #150.
