Thomas Eizinger 578363a7fe refactor(ip-packet): introduce etherparse (#6524 )

This PR introduces the `etherparse` dependency for parsing and
generating IP packets.

Using `etherparse`, we can implement the NAT46 & NAT64 implementations
for the gateway more elegantly because it allows us to parse the IP and
protocol headers into a static and much richer representation. The
conversion to the IPv4/IPv6 equivalent is then just a question of
transforming one data structure into another and writing it to the
correct place in the buffer.

We extract this functionality into dedicated `nat64` and `nat46`
modules.

Furthermore, we implement the various functions in `ip_packet::make`
using `etherparse` too. Following that, we also overhaul the NAT
translation tests that we have in `ip_packet::proptests`. Those now use
the more low-level `consume_to_ipX` APIs which makes the tests more
ergonomic to write.

In the future, we should upstream `Ipv4HeaderSliceMut` and
`Ipv6HeaderSliceMut` to `etherparse`.

Moving all of this functionality to `etherparse` will make it easier to
write tests that involve more IP packets as well as customise the
behaviour of our NAT.

Connlib

Firezone's connectivity library shared by all clients.

Building Connlib

You shouldn't need to build connlib directly; it's typically built as a dependency of one of the other Firezone components. See READMEs in those directories for relevant instructions.
