counties_sf is out of date

[ghost]

The list of counties returned by counties_sf is now out-of-date.

counties_sf() %>%
  filter((name == "Bedford" & state == "Virginia") | (name == "Petersburg" & state == "Alaska"))

See this note, Petersburg, AK needs to have its lsad updated, but Bedford, VA needs to be merged.

Unfortunately the fixes would make this incompatible with the last decennial census, so I'm not sure what the best move is. I guess a year argument to the function call would be the safest, but would require a lot of engineering effort.

this is super helpful! #ty!

I'll figure out a way to work in the year argument but perhaps will shunt in a hacky "current" function just to make sure it's aligned correctly with the real world.

In addition to the changes noted by eamoncaddigan, two counties have been renamed and given new FIPS codes since the 2010 census (both in 2015).
