Noted: check package versions if exactextractr::exact_extract doesn't work as supposed

[KaiyueZou]

raster: 3.4.13
sf: 1.0.3
exactextractr: 0.6.1

Useful code:

# Restore R packages to previous versions 
require(devtools)
install_version("raster", version = "3.4.13", repos = "http://cran.us.r-project.org")
# Check the version of a R pacakge
packageVersion("raster")
