docstr: Returns the set of known tables in the adjustments file in DataFrame
  form.
  
  Parameters
  ----------
  convert_dates : bool, optional

      convert_dates is True, all ints in date columns will be converted
      to datetimes.
  
  Returns
  -------
  dfs : dict{str->DataFrame}
      Dictionary which maps table name to the corresponding DataFrame
      version of the table, where all date columns have been coerced back
      from int to datetime.
