add_stats is used to add the output of a statistical test to a
tidystats list. While adding the output, additional information about the
test can be added, including the type of test (primary, secondary, or
exploratory), whether the test was preregistered, and additional notes.
Please note that not all statistical tests are supported. See 'Details' below
for a list of supported statistical tests.
