- Make each mesh backend use a unique NetworkInfo class and separate connectionQueue and latestTransmissionOutcomes vectors.

- Deprecate NetworkInfo and TransmissionResult classes.

- Add single recipient transmission methods.

- Add a getCurrentMessage method to TcpIpMeshBackend to maintain feature parity when using single recipient transmission methods.

- Increase code abstraction level in transmission methods.

- Remove use of networkIndex except for in constructors, since it can change after each scan.

- Make Espnow backend require at least BSSID to connect, and the TcpIp backend require at least SSID.

- Make printAPInfo method take NetworkInfo as argument.

- Add new TransmissionOutcome class to replace obsolete TransmissionResult.

- Add _scanMutex.

- Improve code abstraction in HelloEspnow.ino.

- Update HelloEspnow.ino example to demonstrate the new features.

- Update and improve comments.
