Add a shadow column to a dataset
Casting a shadow shifted column performs the equivalent pattern to
data %>% select(var) %>% shadow_shift(). This is a convenience function
that makes it easy to perform certain visualisations, in line with the
principle that the user should have a way to flexibly return data formats
containing information about the missing data. It forms the base building
block for the functions cast_shadow_shift, and cast_shadow_shift_label.
It also respects the dplyr verbs starts_with, contains, ends_with, etc.
to select variables.
cast_shadow(data, ...)

One or more unquoted variable names separated by commas. These
