Update ipaddr.js to 2.4.0

[vibhor-aggr]

Fixes #65.

This updates ipaddr.js from 1.9.1 to the current 2.4.0 release. proxy-addr uses the stable ipaddr.js APIs called out in the issue (isValid, parse, kind, IPv4-mapped conversion, netmask prefix calculation, and match), and the existing test suite passes against 2.4.0.

Because every ipaddr.js 2.x release declares node >= 10, this also updates proxy-addr's engines.node metadata from >= 0.10 to >= 10 so the package metadata matches the dependency floor.

Verification:

• npm test
• npm run lint
• git diff --check
• local smoke check for IPv4-mapped address parsing and trust matching with ipaddr.js@2.4.0
