format files. The function should also work with the ZIP file you created,
as long as you do not change the filenames of the original GeoJSON files.

Value
A list of sf::sf() objects.
Examples
path <- system.file("extdata", "castle.zip", package = "fude")
d <- read_fude(path, stringsAsFactors = FALSE)
