[feature request] add GRPC and MUX setting for client side

[SPAK007]

Hi dear xcode75

I want to add mux and grpc/h2 setting in client side. but there is no option to add these settings : i want to enable grpc multi mode only on client side (how to do that?)

e.g "grpcSettings": { "serviceName": "" "multiMode": true, "idle_timeout": 60, "health_check_timeout": 20 }

e.g "mux": { "enabled": true, "concurrency": -1, "xudpConcurrency": 16, "xudpProxyUDP443": "reject" }

e.g "httpSettings": { "read_idle_timeout": 60, "health_check_timeout": 20 } also please add sniffing options to choose from e.g: http, tls, quic

        "sniffing": {
            "enabled": true,
            "destOverride": [
                "http",
                "tls",
                "quic"
            ]
        }
