Modernize, add tests, allow Packet to outlive the callback it's passed to

- Add a pyproject.toml

Fixes for several open issues

…cated netlink socket

The chief use case for this is when `sockfd` was allocated in a different network namespace and passed to the current process over a UNIX domain socket or similar. It allows the current process to use netfilterqueue to manage traffic in a different network namespace.

Add a parameter NetfilterQueue(sockfd=N) for using an externally-allocated netlink socket

Make netfilterqueue a package and add type hints

Release v1.0.0

Check whether payload is NULL before accessing it in __str__

Add Packet accessors for interface indices

Release v1.1.0
