can't catch custom Session when set URLSessionConfiguration protocolClasses about netfox

[Hflydragon]

here config.protocolClasses something errors use? why not use protocolClasses_Swizzled

`@objc private class var default_swizzled: URLSessionConfiguration {
get {
let config = URLSessionConfiguration.default_swizzled

        // Let's go ahead and add in NFXProtocol, since it's safe to do so.
        config.protocolClasses?.insert(NFXProtocol.self, at: 0)
        
        return config
    }
}

@objc private class var ephemeral_swizzled: URLSessionConfiguration {
    get {
        let config = URLSessionConfiguration.ephemeral_swizzled
        
        // Let's go ahead and add in NFXProtocol, since it's safe to do so.
        config.protocolClasses?.insert(NFXProtocol.self, at: 0)
        
        return config
    }
}`
