Bug fixes and improvements

  #15

  get_duplicated_rows().

• The function get_all_na_rows() had a bug when a column was named
  “test”, that has been fixed.

  one column, that has been fixed.
  #14

• The date functions as_any_date(), as_any_date(), as_any_date(),
  have a default format setting which is yyyy-mm-dd. Also if there is
  ambiguity, but 100 % match, the first format will be used as the
  format for the whole column.
  #12

• The function read_any_csv() can handle 3 types of CSV (coma
  separator, semi column separator and a mix of columns containing
  both), which works better. The function also handles (a priori) the
  latin1 encoding Still experimental.
  #10
  #9
