feat: Implement net.cidr_contains builtin (#471)

Major changes:
- Implement the `net.cidr_contains` builtin
- Enable the v0 and v1 test for `net.cidr_contains`
- Add the `netip` crate to standardize CIDR searching and other
  operations

Key Concept:
- Allow users to leverage the `net.cidr_contains` builtin to check
  whether an IPv4 or IPv6 CIDR contains a specified IP address or
  subnet.

Testing:
- All tests passing.
