Version 4.5.0 was not published correctly to PyPI

[AbsurdlySuspicious]

Source tarball on pypi [1] has version 4.5.0 specified in setup.py, but contains no changes related to frequency lists initialization and still contains add_frequency_lists helper function which should have been removed in 4.5.0 according to tagged version on github. Maybe there's more stuff missing, I didn't check everything

add_frequency_lists helper function

I'm also not sure if this removal was intentional. It would be good to reimplement it again if it wasn't.
