feat(transport): rust zenoh client and router support

[aclauer]

Contribution path

• Small, safe change that does not need a tracking issue
• Linked issue or discussion: DIM-XXX / #XXX / URL

Problem

I didn't add zenoh router and client modes because I was lazy and just used peer mode for everything.

Solution

Now we can pass more configs to the Rust zenoh transport:

• mode, connect, listen, mutlicast, interface, gossip

How to Test

from examples/native-modules

python rust_ping_pong.py --transport zenoh <- runs with both modules on peer mode
python rust_ping_pong.py --transport zenoh --topology <- runs with pong as router and ping as client, shows in logs
