With this commit `libp2p-identify` no longer discards the whole identify payload in case a listen addr of the remote node is invalid, but instead logs the failure, skips the invalid multiaddr and parses the remaining identify payload. This is especially relevant when rolling out a new protocol to a live network. Say that most nodes of a network run on an implementation version v1. Say that the `multiaddr` implementation is not aware of the `webrtc/` protocol. Say that a new version (v2) is rolled out to the network with support for the `webrtc/` protocol, listening via `webrtc/` by default. In such case all v1 nodes would discard all identify payloads of v2 nodes, given that the v2 identify payloads would contain the `webrtc/` protocol in their `listen_addr` addresses. See https://github.com/libp2p/rust-libp2p/issues/3244 for details.
