datawizard 0.6.3

MAJOR CHANGES

• There is a new publication about the {datawizard} package:
  https://joss.theoj.org/papers/10.21105/joss.04684

• Fixes failing tests due to changes in R-devel.

• data_to_long() and data_to_wide() have had significant performance
  improvements, sometimes as high as a ten-fold speedup.

MINOR CHANGES

• When column names are misspelled, most functions now suggest which existing
  columns possibly could be meant.

• Miscellaneous performance gains.

• convert_to_na() now requires argument na to be of class 'Date' to convert
  specific dates to NA. For example, convert_to_na(x, na = "2022-10-17")
  must be changed to convert_to_na(x, na = as.Date("2022-10-17")).

BUG FIXES

• data_to_long() and data_to_wide() now correctly keep the date format.
