v3.9.0

🏃 Performance improvement

• Huge performance improvement in terms of request served: about 6x faster!
  @vortigont refactored the part sending bytes over the wire. In our benchmark test, we can now serve with 16 concurrent clients about ~ 70 req / second. Before, we were capped at ~12-13 req / second.

💡 New Feature

URIMatcher was added to handler declaration in order to have more flexibility when defining routes, with or without regex support (-D ASYNCWEBSERVER_REGEX=1). This also applies to Json and MessagePack handlers. See the example and doc at https://github.com/ESP32Async/ESPAsyncWebServer/tree/main/examples/URIMatcher
