SystemError: incompatible with python 3.10

[TitaniumHocker]

When using package with python3.10 this error occurs on using systemd.journal.Reader:

...
reader.this_boot()
  File "/home/ifedorov/.cache/pypoetry/virtualenvs/jviewer-g9vQZSG3-py3.10/lib/python3.10/site-packages/systemd/journal.py", line 376, in this_boot
    self.add_match(_BOOT_ID=bootid)
  File "/home/ifedorov/.cache/pypoetry/virtualenvs/jviewer-g9vQZSG3-py3.10/lib/python3.10/site-packages/systemd/journal.py", line 244, in add_match
    super(Reader, self).add_match(arg)
SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

This error seems to be fixed in this commit, so new release needs to be made.
