Convert CSV of Uptime.com probe servers to Squid proxy config format

csv-to-squid-config.sh

{
    read # ignore first line
    while IFS=, read -r name location address address_ipv6
    do
        printf "%-18s %-15s %-20s\n" "acl whitelist src" "$address" "# $name"
    done
} < probe-servers.csv # default file name

Output should look something like this
