feat(check-ip): print stage timings to stderr

Browse Source 
Always-on "Loading X... Nms" lines on stderr for blocklists, geoip,
and whitelist load stages. Makes it obvious at a glance that the cost
is cold-start parsing (not re-downloading) and surfaces the sizes of
the loaded sets. Stdout stays clean for pipe-friendly consumption.
