Implement opt-in UPnP IGD port forwarding for P2P nodes behind NAT,
enabling inbound connections without manual router configuration.
This is gated behind the `upnp-igd` feature flag.
Changes:
- Add PortMapping trait for pluggable port-mapping protocols (UPnP, PCP, NAT-PMP...)
- Add optional oxy-upnp-igd v0.1 dependency behind `upnp-igd`
- Parse UpnpConfig (enabled, discovery_timeout, lease_duration, description,
refresh_interval) from listener URL
- Periodically refresh external address and publish it to the P2P network
- Add UPnP-specific error handling
- Enable `upnp-igd` feature in darkirc (opt-in; not enabled by default)
Port mappings are created lazily once a gateway is discovered and are
automatically renewed. External addresses are tagged `source=upnp` and
refreshed at a configurable interval.

We should still figure out what to do before publishing darkfi-sdk to
crates.io since it probably can't reference a git version.
This might imply publishing our halo2 fork as well, probably under
halo2-darkfi namespace.
- replace log crate with tracing,
- replace simple-log crate with tracing-subscriber and tracing-appender
- add nu-ansi-term crate as a dependency which is itself tracing-subscriber's dependency,
inorder to write colored outputs to the terminal since we override formatting provided
by tracing-subscriber
Instead of awaiting a `fetch_seeders()` method, there is a pubsub (see `dht.lookup()`) where seeders are send to as soon as they are found, so you can start downloading as soon as you find one seeder.
Before this, you started downloading when you fetched all seeders which increased the initial delay for all downloads.
