Removes a few lines of C++ code while making `isIPv4()` about 3x faster. `isIPv6()` and `isIP()` for the IPv6 case stay about the same. I removed the homegrown `isIPv4()` in lib/dns.js that utilized a lookup table. It is in fact a little faster than the new `isIPv4()` function but: 1. the difference is only measurable at around 10M iterations, and 2. the function is a "probably IPv4" heuristic, not a proper validator
