- `PUBLICIP_API` accepts a comma separated list of ip data sources, where the first one is the base default one, and sources after it are backup sources used if we are rate limited. - `PUBLICIP_API` defaults to `ipinfo,ifconfigco,ip2location,cloudflare` such that it now has `ifconfigco,ip2location,cloudflare` as backup ip data sources. - `PUBLICIP_API_TOKEN` accepts a comma separated list of ip data source tokens, each corresponding by position to the APIs listed in `PUBLICIP_API`. - logs ip data source when logging public ip information - assume a rate limiting error is for 30 days (no persistence) - ready for future live settings updates - consider an ip data source no longer banned if the token changes - keeps track of ban times when updating the list of fetchers
