This function is useful if your data renders differently depending on the
available width. In this case, implement the pillar_shaft() method for your
class to return a subclass of "pillar_shaft" and have the format() method
for this subclass call new_ornament(). See the implementation of
pillar_shaft.numeric() and format.pillar_shaft_decimal() for an example.
new_ornament(x, width = NULL, align = NULL)A character vector with formatting, can use ANYI styles e.g provided by the cli package.
An optional width of the resulting pillar, computed from x if
missing
Alignment, one of "left" or "right"
new_ornament(c("abc", "de"), align = "right")
#> <pillar_ornament>
#> abc
#> de
