This function takes messy column names and returns clean ones that work well with
R by default. Names that are all lower case with no R-unfriendly characters
such as spaces and - are returned.
Examples
# \donttest{
if(curl::has_internet()) {
crashes_raw = read_collisions(year = 2022)
column_names = names(crashes_raw)
column_names
format_column_names(column_names = column_names)
}
