  Body: [Pandas 1.0](https://pandas.pydata.org/docs/whatsnew/v1.0.0.html) removed some functionalities previously deprecated, and some features seems to be broken. For example, trying to fit a FAMD gives the following error:
  ```
  ~/.pyenv/versions/3.8.2/envs/bioinformatics/lib/python3.8/site-packages/prince/one_hot.py in transform(self, X)

       32             data=super().transform(X),
       33             columns=self.column_names_,
  
  TypeError: SparseDataFrame() takes no arguments
