Load district boundaries for a specific year
Note
Other ADM2 years and ADM3 boundaries require the tidycensuskr.sf package to be installed.
No explicit dependency is defind; but users should install the package following
the instructions at vignette('v01_intro') or more succinctly:
install.packages('tidycensuskr.sf', repos = 'https://sigmafelix.r-universe.dev')
