Convert API to package netip

This is a breaking change across the board, but one that is necessary for long-term maintainability and resource efficiency. Upgrading net.IP for netip.Addr is straightforward, so I won't document that here.

If you want to stay on the old API, you can continue using v0.4.1, but note that the 0.4.x series will not receive any further updates.

What's Changed

• Use netip.Addr instead of net.IP by @antoninbas in #36
