datawizard 0.6.4

NEW FUNCTIONS

• data_codebook(): to generate codebooks of data frames.

• New functions to deal with duplicates: data_duplicated() (keep all duplicates,
  including the first occurrence) and data_unique() (returns the data, excluding
  all duplicates except one instance of each, based on the selected method).

MINOR CHANGES

• .data.frame methods should now preserve custom attributes.

• The include_bounds argument in normalize() can now also be a numeric
  value, defining the limit to the upper and lower bound (i.e. the distance
  to 1 and 0).

• data_filter() now works with grouped data.

BUG FIXES

• data_read() no longer prints message for empty columns when the data
  actually had no empty columns.

• data_to_wide() now drops columns that are not in id_cols (if specified),
  names_from, or values_from. This is the behaviour observed in tidyr::pivot_wider().
