Subject: [PATCH] fix: update ipaddr.js to 2.x and support /0 CIDR notation

Closes #65 - Update ipaddr.js to ^2.2.0 (2.x is API-compatible for
proxy-addr's usage: parse, range, match methods)

Closes #28 - Fix 0.0.0.0/0 CIDR validation:
  Change range check from <= 0 to === null || < 0 so that prefix
  length 0 (meaning 'all addresses') is a valid value.
