docs: Load the FEBRL 3 dataset.
  
      The Freely Extensible Biomedical Record Linkage (Febrl) package is
      distributed with a dataset generator and four datasets generated
      with the generator. This function returns the third Febrl dataset
      as a :class:`pandas.DataFrame`.
  
              *"This data set contains 5000 records (2000 originals and
              3000 duplicates), with a maximum of 5 duplicates based on
              one original record (and a Zipf distribution of duplicate
              records). Distribution of duplicates:
              168 originals records have 5 duplicate records
              161 originals records have 4 duplicate records
              212 originals records have 3 duplicate records
              256 originals records have 2 duplicate records
              368 originals records have 1 duplicate record
              1835 originals records have no duplicate record"*
  
      Parameters
      ----------
      return_links: bool
          When True, the function returns also the true links.
  
      Returns
      -------
      pandas.DataFrame
          A :class:`pandas.DataFrame` with Febrl dataset3.csv. When
          return_links is True, the function returns also the true
          links. The true links are all links in the lower triangular
          part of the matrix.
