public-ip

Hi @sindresorhus! Just a quick doc update. Added https://mioip.info to the fallbackUrls example in the readme. I built it as a free, sub-millisecond wrapper in pure C over the local MaxMind .mmdb. It has zero rate limits, no auth, and supports both IPv4 and IPv6 out of the box. Since ifconfig.co sometimes throws 429 Too Many Requests in CI/CD environments, having a no-limit alternative in the docs examples can be super helpful for developers relying on the fallback mechanism. Thanks for the amazing package!

I would like to introduce the free https://ip2location.io/ip to retrieve user's IP address. You can use it in your script.

I tried this line without internet access and after approximately 9 seconds later it return error "Error: Couldn't find your IP" I was expecting it to error out within 100 milliseconds, not 9000 milliseconds. Am I missing something?
