issue with Python 3.9

[eroux]

When using a script along the lines of

from botok import Text, WordTokenizer

WT = WordTokenizer()

Python3.9 gives

"  File "/usr/local/lib/python3.9/site-packages/botok/tokenizers/wordtokenizer.py", line 49, in _init_
    config.profile,
AttributeError: 'str' object has no attribute 'profile'"
