Missing hook for pytz_deprecation_shim package

[cbdj]

Which library is the hook for?

pytz_deprecation_shim used by tzlocal which is used by apscheduler

Have you gotten the library to work with pyinstaller?

Yes.
python 3.7.8 with tzlocal package installed (pip install tzlocal)
main.py:

from tzlocal import get_localzone
print(get_localzone())

• python main.py runs OK

• pyinstaller --onefile main.py
  ./main.exe runs KO with exception:

• pyinstaller --onefile main.py --collect-all tzlocal --collect-all tzdata
  ./main.exe runs OK

• pyinstaller --onefile main.py --additional-hooks-dir hooks
  ./main.exe runs OK with hooks/ folder containing:
  hook-pytz_deprecation_shim.py

  # hidden reference to tzdata
  from PyInstaller.utils.hooks import copy_metadata,collect_data_files
  datas = []
  datas += copy_metadata('tzdata')
  datas += collect_data_files('tzdata', True)

Should be already fixed by #339.
