mme_long returns a data frame containing
exercise-country-year observations of multilateral military exercises.
Built from the MME version 7 data (https://doi.org/10.7910/DVN/KHFODX)
and reshaped so each row represents a single participating country in
a single year of a single exercise. This is the data object underlying
get_exercises().
