lib: use Node.js net lib and reject malformed addresses

[ouuan]

See #143. Given the current API of this library, I believe that it's not suitable to support malformed addresses like 0x7f.1. It's hard to parse them correctly in all cases. It's better to throw errors for them.

This PR uses the Node.js net library so it should be reliable.

I suggest releasing v3 after merging this, because:

1. net.SocketAddress is added in Node v15.14.0 and v14.18.0. I think it's reasonable to drop support for older Node versions because Node 12 has reached end-of-life since 2022-04-30. If the user cares about security, they should use a new Node version.
2. I would consider throwing new errors as a breaking change.
3. Dropping support for malformed addresses could also be a breaking change.

We could try to (partially) fix the security concerns in a compatible way in v2 (and v1) in another pull request.

The maintainer is very inactive. He has no obligation to continue maintaining this library, but I'd suggest switching to a different actively maintained library.

I came across a couple of maintained forks of node-ip:

• https://github.com/eggjs/node-ip
• https://github.com/zaptic/neoip

Both forks are a few months old, so there's not enough activity for me to tell whether they're likely to be maintained in the long term. That said, they may be a good solution for folks who aren't yet ready to switch to an alternative.
