geolocate is slow

[Arkoniak]

geolocate is extremely slow.

With the following setup

using BenchmarkTools
using GeoIP
using StableRNGs
import Sockets: IPv4

db = load(zipfile = "GeoLite2-City-CSV_20210427.zip")

rng = StableRNG(2021)
smp = rand(rng, db.db.v4net, 100)
ips = map(smp) do net
    IPv4(net.netaddr + 1)
end

I have the following results

julia> ip = ips[1]
ip"201.186.185.1"

julia> @btime geolocate($db, $ip)
  278.274 ms (12858984 allocations: 196.22 MiB)

julia> @time geolocate.(db, ips)
 16.092770 seconds (666.95 M allocations: 9.939 GiB, 8.59% gc time)

I use @time because there is no need in BenchmarkTools precise measurements, 16 seconds is way too long.
